Background & History of the Plymouth Rock Chicken

You might be able to guess from its name that the Plymouth Rock Chicken is one of the oldest chickens kept in America. These chickens were named after the famous landing place of the Pilgrims when they first came to America and were one of the first established heritage breeds.

Early Development

Plymouth Rocks were developed in the mid-1800s. There are currently seven color varieties, but the Barred Rock Plymouth was the most popular from the beginning. They were accepted as the breed standard in 1874 .

For unknown reasons, the breed entirely disappeared for 20 years, reappearing in 1869 and sticking around to become one of America’s sweetheart chickens.

Many people claimed to have developed these birds back in the 1800s, and no one has been verified. However, researchers today think that the first Plymouths were developed from Black Java and Dominique chicken lines.

The Plymouth Rock chicken is one of the older American breeds. However, it wasn’t always so popular and has gone through ups and downs among American society’s chicken keepers. The Livestock Conservancy now classes these birds as “recovering” thanks to their renewed notoriety.

World War II

They were the most extensively bred chicken breed in America until World War II due to their outstanding qualities, making it a sought-after farm chicken. The government even encouraged their breeding because of their large egg output and meaty bodies that could offset rations in the war’s worst times.

However, after and during the war, new breeds were introduced. The chicken production industry labeled Plymouths as unfit to meet the modern market’s requirements even though they have a select variety of chicken meat and egg production. 

Modern Homesteading

With the growing trend of keeping chickens personally at home or on a homestead, the Plymouth Rock chickens have found a renewed level of demand. The Barred Plymouth Rock is the most popular color variety of the Plymouth, having beautiful plumage of black and gray bars on each feather.

These chickens are suitable for beginners and for those that are raising chickens as a family homestead. Their laid back nature and general lack of noise make them a gentle “break-in” breed as you begin a flock.

Temperament & Behavior

Plymouth Rock’s personality is one of its most winning characteristics beyond its high-quality, dual-purpose production. These naturally curious creatures can quickly become your feathered friends.

The Plymouth Rock chicken is one of the most docile chicken breeds to raise. With a bit of patience, they rarely get flighty around humans, particularly those they recognize.

They are a good choice for adults beginning to keep chickens and the kids of a family since they perform well around all ages.

Overall, although they are still active for chickens, they have a sweet, docile personality. They have been known to become lap chickens, follow their keepers around, and enjoy getting stroked and attention from you.

Plymouth Rock hens are quite likely to go broody. They aren’t known for their exceptional broodiness, but their tendency is towards it.

If they go broody, they are great mothers, and you won’t have to worry about the chicks wellbeing. Otherwise, you can always use an incubator.

These docile and loving chickens tend to prefer being kept in smaller flocks. The noises they make often sound closer to a “coo” than louder clucking common in other breeds, such as the Minorca chicken.

It is easy to keep a Barred Plymouth Rock chicken in a smaller area or a legalized neighborhood without causing a stir.

These chickens are not known for picking fights with other birds in their flock, even different breeds. They are assuredly lovers, not fighters. 

Overall, Plymouth Rocks are considered a pleasure to own since they enjoy much more human interaction than other breeds and tend to get along with other chickens in their flock. Even the roosters are known for their relative docile nature.

Plymouth Rock Chicken Breed Specifics & Traits

Purposes of the Plymouth Rock

Looking beyond a Plymouth Rock chicken’s winning personality, they are also very useful chickens.

Plymouths are dual-purpose chickens, beneficial for both their egg-laying and meat production instead of one or the other. They lay superior quality, large brown eggs. 

Part of the Barred Plymouth chicken’s dismissal was its supposed inability to meet Americans’ high production demands. Not only that, but pure white eggs have become the accepted standard, and Plymouths lay brown eggs.

Another one of the reasons for their dismissal by the poultry industry was their dependability to produce eggs over their entire lives. A Plymouth Rock hen will do very well in its first three years of life. After that, their egg production tends to steadily decrease until they die.

Luckily for these chickens, brown eggs produced from chickens that haven’t been “improved” have a niche market to themselves. 

Plymouth Rock chickens don’t only make good layers. They are also considered a heavyweight chicken, with males weighing almost 10 pounds. These large bodied birds are excellent meat chickens.

There is a bantam version of the Plymouth Rock chickens that was developed in the early 1900s. However, these are not as popular as the full-sized chickens and are harder to find. Even the Plymouth Rock Bantam has a larger body than most other bantam chickens.

Size and Appearance of the Plymouth Varieties

The standard weight of a Plymouth Rock rooster is 9.5 pounds. The hen’s standard is 7.5 pounds.

Plymouth Rock chickens have been a well-maintained breed from the beginning and have an excellent genetic pool to draw from which they are bred. It is due to this genetic pool that they are known for being long-lived birds. On average, a Plymouth will live around six years, although some Plymouths may live to be older if they are kept as pampered pets than farm chickens.

There are seven varieties of Plymouth Rock Chickens. These include:

Underneath this variety of plumages, they all have yellow skin. The Barred Plymouth Rock (also called Barred Rock) is the most common, with the White Plymouth following behind by quite a ways. 

The barring on many of these color varieties comes from a dominant sex-linked gene. The gene prevents pigment from being expressed on colored plumage and creates light bars on the originally dark black feathers.

Roosters usually are lighter in color than hens because they carry two copies of this gene while the hens only have one.

Other than the Plymouth Rock’s barred plumage, other noticeable characteristics are their bright yellow legs and feet contrasting against the dark feathers.

They have a single comb with five serrated points dispersed evenly across them. The middle points are often the tallest, with the front and back points being shorter.

Their comb, wattles, face, and earlobes are all bright red. 

The appearance of the chicks varies depending on their plumage variety. They are early-feathering birds, and most of the chicks have yellowish plumage under their beaks and stomachs, with shades of black and gray covering the rest of their body.

Hardiness and Health

The Plymouth Rock chickens are a low-maintenance breed overall. They tolerate cold weather conditions and heat quite well.

Although these birds are very friendly towards people they know, they can be extremely flighty around other animals or people close to their coop.

These beautiful birds are also quite healthy. They are relatively prone to dealing with intestinal parasites, but this can often be easily remedied and even more easily prevented.

Other illnesses to watch out for include:

  • Vent Gleet
  • Vent Prolapse
  • Bumblefoot (Pododermatitis)

All of these are treatable so long as they are caught in time. If you notice a sudden decrease in a hen’s egg-laying capacity, carefully look them over to assure their health.


Plymouth Rock chickens mature at an average pace compared to other typical domesticated breeds.

Hens can begin to lay eggs between 18 and 20 weeks of age. Their eggs are shades of soft, light brown, and considered a “large” size.

Plymouth hens can lay anywhere from 200 to 300 eggs each year. On average, they lay closer to 230 eggs each year. You can expect these chickens to produce about four eggs each week.

You can find chicks and eggs sold at almost any hatchery.

On average, a pullet costs between $10 to $15 from a hatchery.

Overall, you can expect great things from the Plymouth Rock Chicken from almost any perspective. Their biggest downside is the hen’s inability to consistently lay as they age, which is typical for most chicken breeds. Otherwise, their friendly, easygoing personalities make them great for beginners, families, and those living in crowded areas. 

If you are primarily interested in their usefulness, you should still be pleased with a dual-purpose chicken. Plymouth rock chickens lay large eggs and provide close to the maximum amount of meat that an “unimproved” chicken will. All things considered, they are worth more than a second look as you start your chicken flock or continue to enlarge it.
