I am having the very same thing with my babies. They one by one seem to be getting whatever it is. I have buried 4 in the past 10 days. Pretty darned sick of this for sure. Does anyone think I should maybe give them some additional tetracycline? They are getting water with homemade electrolytes, the bedding is pine shavings and they have mediated chick starter. All seem happy and full of energy till this bloody disease, whatever, strikes. I have raised baby chicks off and on for 30 some years and never had such difficulties as I have had this year. It's just darned depressing. I have given some of the other sick ones some goldenseal, but perhaps, too late to do any good. It's a head scratcher for sure.
