I just had all 5 of my two month old chicks die. They looked a bit tired yesterday, so I had put them in a separate cage in their coop. I thought that they just needed a rest from the older chicks. This morning in the cage there were three dead chicks. There was bloody poop. I had no idea about coccidiosis. but that is what it is. I took the two that were still alive in the house and started treating with Corid. One already died in the house and the remaining one does not look like it is going to live. The coop that the chicks were in is where I just keep chicks. I know that I need to treat the older chicks that were in that coop. but I was wondering if I should treat all my older chickens and ducks that live in a different coops. I also have baby ducks that are in the same play pen that the baby chicks were in before I move them into the coop. Should I treat the baby ducks.
