How Fast Do Rhode Island Reds Grow?

Like most other poultry, Rhode Island Red chickens grow relatively fast. 

They start putting on weight right away and typically reach their full weight at 40 weeks. 

Rhode Island Red chickens are among the most popular chickens among backyard farmers and homesteaders. 

The main reason for this is their excellence as a multipurpose breed. 

Rhode Island Red hens make excellent egg layers. 

They also are a good meat breed. 

For this reason, they are a great addition to any backyard farm or homestead. 

Having a backyard flock of Rhode Island Reds will keep you and your family with a steady supply of eggs and a decent amount of meat when it comes time for butchering and slaughtering. 

Chickens grow up so quickly. 

It seems like the time between them being baby chicks and reaching their full size happens fast. 

Charting their growth and researching typical growth for the chicken breed gives you a good idea of what to expect as far as growth goes for the first few months of your chicken’s life. 

Rhode Island Red Cockerel Growth vs. Rhode Island Red Pullet Growth

As with many other breeds of chicken, the Rhode Island Red breed typically has larger roosters and small hens. 

Most of the time, roosters tend to pack more weight than their hen counterparts. 

If you are a well-seasoned chicken owner, you’ve undoubtedly recognized how quickly your cockerels seem to plump up than the laying hens. 

In this chart, we break down the weight of cockerels and pullets in 4-week increments. 

You’ll notice how initial weight gain starts slowly and increases significantly as the chicken gets bigger. 

This is the same for both cockerels and pullets. 

You’ll also notice how much more weight Rhode Island Red cockerels put on each week compared to the pullets. 

Here is a great chart to compare the growth rate between male and female Rhode Island Reds. 

Cockerel Weight (in lbs)Pullet Weight (in lbs)Weeks Of Age

When reading this chart, you’ll notice how cockerels and pullets start at the same weight and stay roughly the same until about 4 weeks of age. 

Once your chicks get to the 12-week mark, there is a noticeable and significant difference in the weight between each sex. 

Their similar weight often makes it difficult to identify the sex of chicks when they are very young. 

Weight Gained By Pullets Every 4 Weeks

Most of us keep more hens than roosters in our backyard flock. 

Roosters tend to be territorial and even aggressive in certain circumstances. 

In many cases, you’ll only be able to have one or two roosters in your flock. 

More than this often leads to frequent fighting and stress among the roosters. 

This social dynamic is no different in the Rhode Island Red chicken breed. 

For this reason, most of us Rhode Island Red owners are more interested in the weight gain of the pullets. 

This allows us a good idea of what to expect as far as when they will reach market weight for meat production. 

Since pullets gain weight differently than cockerels, it helps to see the breakdown of their weight. 

This chart shows how much bodyweight a pullet gains every week until 40 weeks. 

At 40 weeks, the pullet is usually at its full weight. If not, just below it. 

You’ll notice how the most weight gained peaks at 8-12 weeks and slowly decreases as the pullet gets older. 

This means you’ll notice a lot of growth at this time in this dual-purpose breed. 

Here is the full breakdown of female weight gain in pounds broken down into 4-week increments.

In general, chicken growth is fairly rigid. 

There aren’t too many things capable of influencing your chickens’ speed or overall weight gain. 

There are a few things to keep in mind regarding weight gain. 

Many people notice some trends when it comes to the growth of their chickens. 

While some are out of your control, some things to consider if you are looking to have your chickens gain as much weight as possible quickly. 

Most people who keep chickens for meat production want their birds to reach their full weight as quickly as possible, so they’re ready for market. 

This makes sense if you raise meat chickens because you’ll collect the profit from their meat much quicker. 

If you plan to keep Rhode Island Red chickens for meat, keep these key factors in mind to quickly get your chickens to their market weight. 

Month Of Birth

When chicks are born, the time of year influences their weight gain and growth. 

Generally speaking, those chicks born earlier in the breeding season tend to put on more weight faster than those born later in the year. 

If you want chicks to grow quickly and put on weight fast, make sure you get chicks born in early February. 

These are often the first chicks of the season, and many reports these early birds grow significantly faster than those born in late April. 


Like all living things, Rhode Island Red chicks need sufficient nutrients and high-quality feed to grow quickly and healthily. 

For the most part, this won’t influence weight gain significantly. 

However, malnourished chicks will not gain weight quickly and may even get sick or die if they don’t receive proper nutrients. 

It may help find a supplement or vitamin to add to the chicken layer feed to ensure your chicks are getting a balanced diet where all their nutritional needs are met. 

It also helps to make sure to monitor their feed intake.

This way, you’ll be sure they are eating enough. 

Practicing good habits when feeding our chickens is essential for their entire lives. 

Our egg layers of the flock need proper nutrition. 

Poor feed leads to decreased layer production and lower egg weight. It will also decrease their weekly laying rate.

  • Orange/red eyes
  • Single combs or rose combs on roosters
  • Vivid coloring on combs, wattles, and earlobes
  • Reddish-brown beaks
  • Yellow feet, sometimes with red coloring

They tend to have coats of a lighter shade of red. 

Like the roosters, they also have black lacing. 

Rhode Island Red chickens are popular among chicken keepers and backyard farmers. 

In more recent years, their popularity has led to significantly deeper colors throughout their coat. 

The early versions of this breed were not bred for looks, so they didn’t have such striking plumage.

The two strains are called Industrial and Old-type. 

The Industrial strain tends to produce smaller and less vivid colors than the Old-type. 

Temperament of Rhode Island Red Chickens

Knowing the temperament and traits of chickens before you bring them home is very wise. 

Some chickens tend to be better for beginners, while others require more experienced care and knowledge. 

Rhode Island Red chickens are an easy dual-purpose bird for beginners but don’t expect them to be friendly or eager to snuggle up with you. 

Some people find Heritage birds friendlier than those commercial birds from hatcheries. 

This is a common observation among Heritage breeds. 

Most Rhode Island Red chicken owners felt their chickens were on the mean side of things as far as personality goes. 

However, personality is a bit of a dice roll with this breed. 

The head rooster of the breed, like most others, tends to be significantly more aggressive and territorial than the hens. 

Rhode Island Red chickens are bred widely as they are a very popular breed.
