One of my younger hens ("Pip") is roughly four months old, and she's also the smallest hen in her flock. I notice that when she's walking, she keeps stepping on her own feet, sometimes making her stumble or trip. She acts perfectly normal otherwise, and is one of the friendliest chickens I've had. I guess my question would be if anyone else has had this issue, and if so, is there anything I can do to help her correct it? Some kind of vitamin Supplements maybe? Thanks a bunch!
