Hello, maybe somebody can help me understand the reason behind my problem. My 7 month Easter Egger is having a hard time getting and repositioning herself on the roost. I noticed her right leg seemed more unstable than the left during the day. When I went to check on her this evening as she was getting on the roost, she had difficulty jumping and not sliding off of it. As soon as she tries to turn around, her right foot slips off and she can't seem to control it well. I have five chickens and only one with this issue. I also noticed the other four picking on her as evidenced by her while feathers all over the coop and run. After a few failed attempts of getting on the roost, she gave up and moved into the nesting box (positioned much lower than the roost). I know chickens are not supposed to sit there overnight, but I feel so bad for her, I don't want to cause more stress. I am so lost, what should I do?
