A 1-week chick weighs around 0.2 to 0.3 pounds, 4 week old around 0.9 to 1.2 pounds and 8 weeks old (broilers) around 4 to 5 pounds. Adult chickens like Bantam weigh 1 to 2 pounds, Leghorn around 4.5 to 6 pounds, Rhode Island Red: 6.5 to 8.5 pounds, Plymouth Rock: 7.0 to 9.0 pounds and Orpington: 7.5 to 10 pounds.
How Much Does a Chicken Weigh?
When you’re curious about the weight of a chicken, it’s essential to know that different breeds and stages of growth can influence the weight.
Let’s dive into the various factors that will help you understand how much your chicken might weigh.
Chicks and Adolescents
The weight of chicks varies based on their age and breed. Here’s a general guideline for how much chicks weigh at different ages:
- 1 week old: 0.2 to 0.3 pounds
- 4 weeks old: 0.9 to 1.2 pounds
- 8 weeks old (broilers): 4 to 5 pounds
Your chicks will continue to grow and gain weight until they’re around 16 to 20 weeks old, which is when they typically reach adult size.
Adult Chicken Weight
Adult chickens’ weight varies greatly depending on the breed. Here are some common breeds and their respective average adult weights:
- Bantam: 1 to 2 pounds
- Leghorn: 4.5 to 6 pounds
- Rhode Island Red: 6.5 to 8.5 pounds
- Plymouth Rock: 7.0 to 9.0 pounds
- Orpington: 7.5 to 10 pounds
Keep in mind that these are average numbers, and individual weights may differ.
Sex differences
The gender of a chicken also plays a part in its weight. In general, hens (female chickens) weigh lighter than roosters (male chickens).
For example, a female Rhode Island Red usually weighs around 6.5 pounds, while a male can reach up to 8.5 pounds.
To give you a better idea of average chicken weights, consider this table:
| Chicken Breed | Average Hen Weight | Average Rooster Weight |
|---|---|---|
| Bantam | 1.5-2.5 lbs | 2-3 lbs |
| Plymouth Rock | 7-8 lbs | 8-9.5 lbs |
| Rhode Island Red | 6-7 lbs | 8.5-9.5 lbs |
| Jersey Giant | 9-10 lbs | 11-15 lbs |
| Brahma | 8-10 lbs | 10-12 lbs |
Remember that these weights are approximate, and individual chickens may weigh more or less than the average for their breed.
Additionally, the purpose of the chicken can also impact its weight. Chickens raised primarily for meat, called broilers, often weigh more than those kept for egg-laying.
While knowing the average weight of a chicken is helpful, remember that factors such as diet, environment, and genetics can influence the weight of a bird.
Giving your chickens proper care and nutrition will help them reach their full potential in terms of size and weight, regardless of their purpose on your farm or homestead.
Factors Influencing Chicken Weight
Breed
Choosing the right breed is the first factor affecting your chicken’s weight.
As mentioned, different breeds have varying sizes and body types, influencing their overall weight.
Diet
A well-balanced and nutritious diet plays a crucial role in your chicken’s growth and overall weight. You should provide:
- Quality Commercial Feed: These usually contain a mix of grains, proteins, minerals, and vitamins, which cater to your chicken’s nutritional needs.
- Proper ratios: Younger chickens require higher protein content (around 18–20%), while adult laying hens need less protein (around 16%).
- Supplements: Nutritious treats and supplements, like vegetables or mealworms, can be given in moderation, contributing to a healthy diet.
Remember to keep clean water available at all times for your chickens.
Age
As chickens age, their weight changes due to growth cycles and egg production. Chickens usually go through the following stages:
- Chicks (0-8 weeks): Chicks gain weight rapidly during the first couple of weeks, but their growth rate varies depending on the breed.
- Pullets (8-18 weeks): Pullets continue to grow and gain weight, but at a slower pace compared to chicks.
- Laying hens (18-22 weeks onwards): Once chickens reach egg-laying age, their weight gain slows down significantly.
Keeping these factors in mind will help you have a better understanding and expectation of how much your chicken may weigh.
Weight Variations in Roosters and Hens
When it comes to chickens, there’s a notable difference in the average weight between roosters and hens. Understanding these variations will help you make informed decisions about which breed may be best for your needs.
Roosters
As mentioned, roosters tend to be larger and have more impressive plumage. On average, a standard-sized rooster can weigh between 6 and 10 pounds, depending on the breed.
Hens
In contrast, hens are usually smaller. Most hens weigh somewhere between 4 and 8 pounds. However, there are exceptions, such as the Brahma hen, which can weigh up to 14 pounds.
Keep in mind that these weights are for mature chickens; chicks will be significantly lighter.
Generally, larger birds consume more feed, while smaller breeds are easier to accommodate in limited spaces.
As you can see, there are many factors that influence the size and weight of chickens. Keep in mind these variations when selecting a breed, and always prioritize the well-being of your flock.
Commercial Chicken Weight
When you’re considering the weight of commercial chickens, it’s important to remember that there are different breeds, and their weight can vary accordingly.
In general, commercial chickens are raised for either meat or egg production, and their weight tends to reflect their purpose.
Meat Chickens
For meat chickens, also known as broilers, they are typically harvested around 6 to 7 weeks of age. At this point, their average weight is around 5 to 6 lbs (2.3 to 2.7 kg) for males and around 4 to 5 lbs (1.8 to 2.3 kg) for females.
However, this weight can vary depending on the specific breed and the conditions in which they’re raised.
That said, here are 5 ways you can increase a broiler’s weight:
Egg-laying Chickens
For egg-laying chickens, their weight primarily depends on the breed. The following are some common egg-laying breeds and their approximate weights:
- White Leghorn: 4 to 5 lbs (1.8 to 2.3 kg)
- Rhode Island Red: 6 to 7 lbs (2.7 to 3.2 kg)
- Plymouth Rock: 7 to 8 lbs (3.2 to 3.6 kg)
- Sussex: 7 to 8 lbs (3.2 to 3.6 kg)
Keep in mind that these are just average weights, and individual chickens may weigh more or less depending on factors such as diet, environment, and genetics.
It’s always a good idea to consult with a poultry expert if you need specific information for your flock or individual birds.
As such, meat chickens tend to weigh more due to their fast growth, while egg-laying chickens’ weight is influenced by their specific breed.
Backyard Chickens Weight
When it comes to raising backyard chickens, one of the crucial things you should know is their weight. Here, we will discuss the usual weight range of backyard chickens for your reference.
Backyard chickens come in different breeds and sizes. Typically, the adult weight of a chicken can be grouped into three main categories:
- Bantams: These small-sized chickens usually weigh between 1 and 2 pounds. Some popular bantam breeds include Sebrights, Silkies, and Cochins.
- Lightweight or Small Breeds: Your lightweight backyard chickens typically weigh between 3 and 5 pounds. Examples of these breeds include Leghorns, Anconas, and Andalusians.
- Heavyweight or Large Breeds: The large-sized chickens in your backyard can weigh from 6 to 10 pounds or more. Examples of these breeds include Plymouth Rocks, Rhode Island Reds, and Orpingtons.

Useful Tools and Methods to Measure
To help you track your backyard chickens’ weight, here are some useful tools and methods:
- Kitchen scales: Small chickens like bantams can be weighed using a kitchen scale. Make sure the scale is clean and sanitized before use.
- Portable pet scale: For larger chickens, a portable pet scale can be a more appropriate choice. Just place your chicken gently on the scale and record its weight.
- Hanging scale and harness: Some people prefer to use a hanging scale with a harness for weighing their chickens. The chicken is placed in the harness, and the scale provides an accurate weight measurement without stressing the bird.
By knowing the weight of your backyard chickens and regularly monitoring their growth, you will be more informed about their well-being and prepared to address potential health issues.
So, always make sure to keep an eye on your feathered friends and ensure they remain healthy and happy in your backyard.
