The smallest adult chicken can be as small as 1.1 pounds while the largest can get up to 13 pounds depending on their breed; there are rare exceptions that go beyond this scale. A chicken’s potential weight is predetermined by their breed but feeding regimens and habitats can cause variants.

The weight of a chicken is not a simple question to answer. There are so many different factors that influence the weight of a chicken. While the one that you roast for dinner weighs a certain amount, the one that laid the eggs for your breakfast weighs a totally different amount. 

It takes about a year for a chicken to reach full size. Under this age, hens are called “pullets” and males are called “cockerels.” Chickens raised for meat are usually slaughtered at this age as the meat has a more tender texture and milder flavor than an older bird. A fryer, or meat chicken, will usually weigh 4.5 to 5 pounds at slaughter. Depending on the breed, this could be quite a bit smaller than the chicken’s natural full size. However, fryers do tend to grow at a faster rate than other chicken breeds

What Are The Heaviest Chicken Breeds?

​Generally speaking, the heavier chicken breeds tend to be those that are raised specifically for their meat. This makes sense, as the intention is to get as much meat from the chicken as possible in a very short amount of time. However, ​premature slaughtering ​of chickens results in them weighing much less than their maximum potential weight.

Among the heaviest chicken breeds are Brahma, Cochin, Orpington, and Jersey Giant chickens. All of these breeds are quite sizable, averaging between 8 and 10 pounds at their fully-grown size.

What Are The ​Lightest Chicken Breeds?

On the other end of the spectrum are chickens that weigh very little. Chicken breeds such as the Cubalaya, Ancona, California Gray, and Leghorn have hens below 5 pounds and roosters below 6 pounds. These smaller breeds tend to be used as egg producers, but are sometimes also used for their meat depending on growth rate and quality of the meat.

Have They Always Weighed The Same?

Did you know that the average weight of a chicken today is a lot different to 50 years ago? Over the decades, the average weight of a chicken has changed a lot. 

Chickens are bred most often for either egg production or for meat. As you might imagine, this factor influences the weight of the particular breed. And for a number of reasons, including selective breeding, chickens have become much heavier. 

Why Has It Changed So Much?

Selective breeding is the practice of breeding only chickens that have a particular trait that you want to replicate. So if you want a chicken with red feathers, you only breed chickens with red feathers. That way, there is more chance that the baby chickens will only have red feathers. The more you do this, the more chance you will have of only getting red feathered chickens from a fresh batch.

  • Stand on the scale and make a note of the weight. 
  • Don’t panic! Remember, you’re wearing clothes and shoes (we assume) so your actual weight will be lower.
