I bought 17 sexlink chicks Monday,they ranged from 3 to 5 days old.When we got home one was droopy and not moving much and she died the next day.I assumed maybe she was injured on the way home.I noticed a couple of the other chicks were droopy and thought maybe it was stress from the trip.Some of them are still droopy and they seem to sleep a lot.It seems like only the smaller chicks are this way the larger ones are doing great.Last night I noticed one that is clearly sick.He is small,droopy,doesn't eat and gets knocked over easy.I am going to the feed store to try and find some Corid.Do you guys think this is Cocci or something else?I've read it's contagious and fast spreading so wouldn't the other chicks be sick already?
