Has anyone had this problem with their chickens? A friend of mine has it happening too. A local vet said several people have been taking in chickens for this. Mine have not been around other chickens and have been sneezing for two weeks. I treated with sulmet which didn't help. Then one got swollen eyes and I gave her 3 shots of LA 200. Cleared it up. Then a rooster started rattling and I gave him a couple injections and he's better. I put them all on Duramycin 3 days ago and the sneezing is starting to get better. The ones who are just sneezing have no eye or lung problems.Any suggestions??
