I'm not sure if I should be worried or not. I'm on day 11 and just about half the eggs have blood rings (13 out of 28). The majority of the blood rings are from my cream legbars. I only get 3 eggs a day from them, so I put in some older ones, 19 cl eggs total and 6 are still alive. (3 didn't start developing) Should I be worried about this? Are cream legbars hard to hatch? I've never gotten very many to hatch, even under my broody showgirl. I don't know if I just have sucky birds or if it's the breed or they have to be extra fresh to make it to the end.
