If you want to raise chickens the organic way one of the most important things is to not over crowd your chicken coop. My coop is 10’ x 40’ and I only have 9 chickens in there. Since they have plenty of room they don’t get stressed from fighting with each other and they never get sick.
The sleeping perch (also called a roost) is also very important. You want it to be very sturdy because the hens can get pretty chubby after a while. You don’t want the perch to be wobbly at all.
If your backyard chickens aren’t over crowded, and they have a nice sturdy perch to sleep every night they’ll be happy and lay lots of eggs for you.
