A week ago we moved our 7 week old chicks into the adult coop. Overnight we lost 5 chicks and 5 more during that day. Also lost a couple in our brooder that had 2-4 week olds in it. We took some of the dead ones to our local school of agriculture and after autopsies, coccidiosis was determined to be the culprit. We immediately separated them from adults and started both the older chicks and ones in brooder on Corid. We have lost another 15 older chicks and 5 young ones since. Over last couple days we still wake up to a dead one though it has definitely tapered down. With only 12 survivors left of the older hatch can I expect any survivors at this point or am I going to continually lose them 1 or 2 at a time? (no losses of younger ones in 3 days) We stopped the Corid yesterday per directions and now still on medicated feed and vitamin supplements in water. So frustrating to lose so many. Any help or suggestions appreciated.
