We have had trouble breeding Black Copper Marans. Hubby and I have tried twice in our incubator. The first try we had a dozen eggs and only 3 hatched. The first one hatched perfectly, the second one hatched with a deformed hip with a bad leg. At first we thought it was splayed, but it turned out to be a deformity of the hip. He's a few months old and we decided to keep him as a pet and name him Lego. He gets around well, although he limps. And the third one we had to help him break his shell after 2 days. We feared he would die. He turned out perfect. Now the second dozen eggs of Marans didn't hatch. However there was a peep hole for day and half and we helped it. The chick doesn't have eyes so we plan to cull it. We can't let him suffer, but we tried to save him. None of the other eggs hatched. We also had some Black Jersey Giants with the second batch of Marans, and most of them hatched perfectly. So it's not the humidity and temperature. I don't know what we are doing wrong why we have such bad luck with the Marans? Has anyone had this same problem?
