I have a Cukoo Maran hen sitting on about 15 eggs and a yellow/brownish mixed breed sitting on about 5. It is day 22 for the Cukoo Maran and day 20 for the mixed breed and nothing has hatched... normal..? Yesterday I candled about 4 eggs each from their nests and I couldn't see anything inside them. they were completely black. I could see nothing but an air sack. If I can only see solid black (and nothing moving) does this mean just an over growth of bacteria? A dead chick inside? Or just a chick ready to come out soon? No blood cells in sight. I'm Kinda confused... I only saw one egg that visibly had something alive and kicking, in it almost looking too big to fit in the shell. Lol Help, somebody!!
