We got two new hens last Friday (4 days ago) and noticed today that one has a foamy eye. I've been reading around and this appears to be a respiratory infection, and I hear it's highly contagious. Of course all the hens are stressed because of the two newcomers. This is a young hen (with almost no comb,) and I paid $7 for her. She's eating and drinking fine, but is getting hen-pecked as the other hens assert their dominance. Now I'm concerned my 4 original hens will have this too, as it's been 4 days! Any advice? There are no chicken vets around, and I hear you cannot buy antibiotics from the store anymore.
