She keeps sitting on the eggs that the other chickens hatch, and if she's had them warm for 1 or 2 days (sometimes I can't collect the eggs til the 2nd day) is that still OK to cook with? Most of them look normal inside, and (not to be gross) but I did notice one or two that had tiny bits of blood which I assume is the very earliest stage of chicken embryo developing. But I need a lot of eggs to bake some cakes with... Anyone know?
