My br is having the same issue with limping. Just checked her foot and it looks totally fine. She usually won't let me touch her, but she let me take a good at her foot/leg tonight. She's up on the roost so it must be not so painful as i would think she would be in the nesting box if it really hurt bad. I think she jumped down one am from the roost to the coop floor and hurt it in some way. She's trying to sit on the roost with 1 foot all the way on and lifting the other. Anything i can do? Asprin?
