Clapton ate some raw yolk even when he was feeling poorly. I think there is probably more goodness in it raw as well. It must be good as it has everything chicks needs to develop. A tiny bit of milk mixed in it might help as well. I also read that egg is the ultimate form of protein, even better than fish or chicken. I read on a site recently where a woman gives her cat a raw food diet. She gives her cat one egg yolk a week for "a glossy coat and bright eyes"
