We had 4 peachicks we hatched in an incubator. They are 1 1/2 weeks old. Today one died. The others have become SO thin, and weak. They're in a stock tank brooder with a heat lamp over one side of the tank. Temp at ground level is 95-97 and the tank is 4' round so they can get away from the heat if they want. I've had game bird crumbles starter for them, and have chopped up little bits of grass for them. Today I started giving them a mixture of whole beaten egg mixed with a little electrolyte, by oral drench via avian drenching tube. I also made a wet mash for them of the crumbles mixed with lukewarm water, given in a shallow lid. I can't figure out why they are so thin. No other obvious symptoms that I can see. What to do? Thanks in advance.
