We have 4 chickens about 18 months old and one has always been the bottom of the pecking order. She is very complacent and sweet and never challenges the others. But lately 2 of the chickens are constantly chasing her away from the food and she has been kicked off the perch they share at night. We make sure she gets enough to eat, but with the cold weather coming I am concerned about her staying warm if the others won't let her near them. Now she sleeps as far away from them as she can get, to the point of hugging the wall. My daughter would be heartbroken if anything happens to her. A friend of mine suggested bringing her inside on cold nights, but I am wondering if this will just make the others pick on her even more. Any suggestions???
