I purchased some month old silkies from a breeder in Florida. I purchased 6. Plus 2 packing peanuts(pets) Ever since they arrived I had one sneeze. No watery eyes or fluid coming out of it's nose. I thought it was the chips so they were moved onto sand. No change. Preety soon another one started to sneeze. They are big enough now that they moved into a stall. I finally broke down and purchased some teramizyn (spell?) to put in the water. no change. One of the little splashes is not doing well now. She is eating and drinking fine. But skinny and has her tail and wings down. Follows me around. The other two still sneeze all the time and seem to wipe there head on their back. I pulled some little feathers that were by their eyes. I am not sure what to do? I was thinking of trying dewormer? They are not around my other chickens. They aren't on any grass. They are eating flock raiser and scratch and peck feed. Refill water every day. On a different note.. My adult silkies still get mites. I finally decided to use frontline. They have been on it for two months. I tried Ive. Dusting every other day for a few days. There coop is cleaned out once a month. They free range during the day. Any other suggestions? At three weeks into a dose they are starting to itch a lot. So will have to dose them again. Very frustrating especially since I have to throw away what eggs they lay. I live where it's wet all the time and my adults are getting up there in age . Youngest being 2. Oldest being 7. So I heard the older they get the more they are likely to get mites.
