Last night, my husband noticed one f our eight week old keets dead in their hut in the garage (heated). I went out to investigate and found that of our 16, 9 were dead. I brought the remaining 7 into the broader in the house for the night, gave them sugar after soaked feed and some warm water with Vet Rx in it and six perked right up. The seventh died overnight, but the remaining six seemed pretty lose to normal, talking and active. I spent the morning bleaching their hit and the garage floor, etc. When I came it at lunch, they were all acting like the one who died last night: feathers fluffed, lethargic, quiet. They don't ring from me if I try to pick the up, which is highly unusual. Their heads are nearly bald and a bit crusty. I don't know if this is part of feathering out or part of the illness. Does anyone know what this is or what I should do? Is it a lost cause at this point?
