I am hatching buff orpingtons. This is my second batch. they have just started hatching in the last few hours and one of them has a very swollen head. the last batch I hatched most of them had swollen heads or necks or both. I posted about it then too, but nobody had heard of that before. as far as I know(I sold them), the chicks with the problem grew up to be healthy and the swelling went down within several days after hatch. I suspected that perhaps I didn't turn the eggs enough, so this time I turned them more regularly. Could it be a genetic problem? could it be viral or bacterial? It just looks like extra liquid in the tissue. it doesn't look healthy. any explanation would be appreciated. thanks!
