I have a, what was sold to me as a barred rock, but appears to be a barred rock possibly mixed with an easter egger type chicken. When I went out to the coop yesterday she was in the hen house sitting on her butt with her legs straight out in front of her. well i brought her up to my deck and put her in the sick chicken box and she is either on her butt sitting or sitting on... for lack of knowing anything else to call it her elbows. she does stand and walk and scratches at the ground but not for very long and she back on her elbows or butt. what could be causing this and should I keep her separated from the rest of the chickens? She is eating pooping good solid regular chicken poop lol drinking everything is normal except the way she is sitting so often and how she is sitting. sometimes when walking she steps on her own foot too. i have googled til my eyes bugged out and have gotten nowhere!
