I picked up a few more mixes from a friend. I had gotten a few a few weeks from him and decided I needed a few more. All these birds had been born together so I just made them all their own coop, so the second batch I saw no reason to quarentine. Ass I was adding the newbies to the coop I noticed one sneezing. and seperated him from the others. He is a silkie mix BTW Unfortunatly the sneezing has not stopped but he shows no other symptoms. and only seems to sneeze when standing up. at least I think it is a sneeze. When he is up and active he will sneeze about every minute or so, just oe sneeze at a time. No amonia in coop, brand new with brand new shavings. I read the other sneezing posts and I am worried. He is seperated but in the garage wioth the others I plan on getting him outside to be really quarentined but am afraid it is too late since he has been sharing the same air space with my others. So far everyone looks healthy. Does sneezing always end badly? other than some yogurt, vinager in water, and some vitamins what can I do. Has this ever happened to anyone elses chicken with a good ending????
