We just started our own flock this year with 2 Buff Orpingtons, 1 sexlink and 1 Ameraucana. One of my BO's Honey, has been limping for a while. I had checked her feet for sores - there were none. Sometimes her wing droops, and sometimes I find her sleeping during the day and not running around with the flock. She eats and drinks fine and I've seen her chasing grasshoppers and acting fine despite her limp. She had a slight nasal discharge which I tried treating with VetRx, and just today I noticed that one of her eyes is watery looking. I just don't know what to treat her with. I've tried giving her grapefruit seed extract initially to help with the limp, but it has not gone away. Should I give her antibiotics?
