My bantam wyandottes were not hatching eggs all year so I kept on trying since January I only know hatched 1 little baby last weekend. The eggs that didn't hatch were fertile some just didn't hatch others weren't fertile and most died before the were done growing in the egg. I know I don't have parasite in my incubator as I've hatched probably a hundred Cochins leghorns and white bantam wyandottes but no silver laced. The hatched quite a few last year but only one this year. Does anyone know what's wrong and how should I help the one chick that's hatched?
