One of my 5 week old sebrights is not doing well. It is very lethargic and is just laying down with eyes closed. Seems to be breathing heavily. Poop seems okay and body weight seems similar to other. I did see it eating and drinking yesterday. Unfortunately, I had to leave for work so I can't check on her again for 8 hours. I gave her some sugar water, in the hopes that it may perk her up. I am going to have my husband check on it but he is not that familiar or comfortable with the birds. Any ideas what it could be? Suggestions to try? I only have 2 sebrights so if I lose this one the other will be alone. It is doing great. I have 10, 5-6 day old bantams in the same room but not the same brooder. I know that chicks do better with others but I would be leery about putting the other sebright in with the babies if its sibling dies. Any recommendations?
