As fun and entertaining as chickens are, they have no compassion and no mercy when it comes to their fellow chickens and can be downright mean to newcomers and those who are hurt and weak. Not that I am faulting them for it, that is just how chickens are, and as chicken owners we have to find ways to work with them and keep everyone from getting hurt.
One of my hens hurt her leg a few weeks ago and lost a lot of her strength and the ability to scratch for worms and dig in the dirt. It soon became evident the the other hens were picking on her, stealing her food, and chasing her away from the feeder. It got to the point where she would just cower in the corner or limp in the other direction if the other hens even came near. When she started loosing massive amounts of feathers, and was getting weaker, I realized that if I kept in her with the rest of the hens, she would never get the nutrition she needs to heal, and might even starve to death.
New feathers coming in!
So I fixed her up a cozy little spot in the animal barn to sleep at night and let her free range all by herself for several hours each day before letting the other four hens out of the chicken coop to make sure she gets some peace and quiet and the first choice of bugs and kitchen scraps. She perked up in a couple of days after being separated, new feathers are growing in, and her leg has healed enough for her to start doing some minor digging again. She is still terrified of the other hens and runs in the other direction when I let them out to free range.
The little barn. It doesn't look like much on the outside, but it is warm and cozy on the inside.
One of the stalls inside the barn with a warming light. I thought she might try to roost in the coop at night, but no, she heads off to the little barn instead of going to the coop with the other chickens. And that is just fine with me.
