Sorry if I am asking again but I don't see my earlier post. I have some baby chicks 7wk. old. One started sitting all the time with its eyes closed. Once in a while it would flick it head. ( not shake just a flick ) Now I am noticing another one or two starting to do the same thing. I have checked thoroughly for mites or lice. Do not think it is mites or lice. A.m. tomorrow am going to remove from brooder box hose down pen with bleach solution put clean play sand on floor. Does any one think I should treat with some antibiotics? If so what kind, how much. These are some very expensive chicks. I do not want to loose them. Any help or suggestions would be appreciated ! THANK YOU !
