To know when should you cull your chicken, you must be familiar with the different types of chicken breeds. Some of the most popular, and common chicken breeds are:
Broilers or Fryers
These birds are at their peak growth at about 7 weeks old. At 7 weeks old these birds weigh about 2.5 to 4.5 pounds. Broilers provide good meat, and it is recommended that you should save your broiler hens to increase your egg-producing chickens.
These birds are at their peak growth at about 3 to 5 months old. At this stage, these birds weigh about 7 pounds. Roasters provide good meat and should be roasted whole.
Older hens as the name suggests are old, and at this age, most of the hens stop laying eggs. Hence, they can be eaten in the form of stew. In addition to this, the meat of these chickens should be cooked for a long time because their meat is a little bit tough than broilers or fryers.
