How Much Do Chickens Weigh?

​Taking into account all of the weights of the different breeds of chickens in existence, the average weight of a chicken tends to be around 5.5 pounds (2.5 kg) for hens and 7.5 pounds (3.4 kg) for roosters.

​Generally speaking, the heavier chicken breeds tend to be those that are raised specifically for their meat.

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.

How To Weigh A Chicken

Now you know how much your chicken should weigh. But how do you find out how much they actually weigh? You can invest in some specially designed animal scales if you like, but there is a simple way if you have your own accurate bathroom scales:

  • First, take your scale out to your chicken run and find a flat, stable surface
  • 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. 
  • Next, grab your chicken and get back on the scale and make a note of the new weight. 
  • Finally, subtract the first reading from the second reading and you have your chicken’s weight!

What If My Chicken Is Underweight?

If any of your birds are underweight, try supplementing their feed with a growth or layer ration for extra carbs and protein. You can also throw them a handful of scratch or cracked corn as these will provide a boost of calories to help them gain weight fast.

And make sure your chickens always have access to food whilst they’re awake. They’re not used to just eating a meal once or twice a day – they much prefer to graze throughout the day as they please.

An underweight chicken may just be going through a growth spurt, in which case they should soon regain weight if you follow these steps. However if they are unable to reach a healthy weight they may be suffering from parasites or a serious illness and you should consult your vet.

What If My Chicken Is Overweight?

You might think an overweight chicken is just living a good life, but it can be very bad for their health, give them difficulty laying eggs, and sometimes cause a prolapse (WARNING – not pretty and very unpleasant for your chicken!).

If you have an overweight chicken you’ll need to reduce the number of treats they get and ensure they always have access to a proper layer feed. You can still give them fruit and vegetables, but calorie heavy foods like scratch or cracked corn should be kept well away from them.

Exercise is important too. Make sure they get plenty of time outside their coop during the day, and as much space as possible to roam around and burn off excess calories. Our automatic door openers mean they can get out and about whilst you’re still in bed.
