Only one of my baby chicks survived the night last night. I came home and they all seemed fine, I replaced their water and an hour later I came back in to check on them and 3 were dead in the sawdust under the heat lamp. Then in a matter of thirty minutes 2 of the remaining three got very slow and unsteady and eventually convulsed and died. No blood in their stool and they were not wet. They were all different types from different sections at the hardware store. This is also my second time raising chicks and I didn't lose any of the last 6. Anyway, I want to do anything I can to help the last one make it. Has anyone heard of this many chicks dropping so close together in time, parasites, disease? Is there a danger to the adults if this lone survivor is integrated into my flock?
