We are having trouble keeping our peachicks alive. I live on a hobby farm and our peahens hatch their chicks in the henhouse. By about 2 weeks old, the peachicks start to display signs of illness: lack of appetite, weakness, droopy wings. It almost looks like blackhead, but they continue to eat and drink (not robustly though). The symptoms seem to last a few days, then they die. I do notice slight diarrhea as well. Can anybody help?
