I have a friend that has chondro's and his male went 7 months without eating he was loosing alot of weight he would show no interest in rats or mice. I got a just hatched baby chicken and took it over there he ate it. Right now I actually have a chicken egg in my incubator to try to feed him another one. It still has about two more weeks before it hatches but I am hoping he is going to eat it too.
