i have a buff orp who is about 7 weeks and shes just as big as when i got her at 4 weeks. her back feathers are just now coming in and before that the skin was bare. under her wings are still bare. today i found her hip had a pretty bad cut. i also found a scab near her wing. she is tiny and im really worried about her. what cold be causing this? i have separated her from her brothers and sisters and from the older flock. she is the brooder with no light and is happy. she is just as energetic as others and eats just as much as them why isnt she growing?
