Hi, I have 2 chooks, 2 and 4 and 4 years old. They were laying alternate days. (currently both on strike). We have noticed that one of the hens eggs, is a bit weird in the egg white. Part of the white is very opaque and solid, and the other part is what I would call normal. Any ideas? I have looked at 'thepoultrysite.com' and can't find anything here..........Thanks.
