What all do you have in there?
Mine are hatching today too. I had 14 eggs: my Black Langshan rooster over Black and White Langshan hens. 4 of the WL hens' chicks are out and one of the BL's. Oh, and I put 3 WL eggs from the incubator under my broody BL hen, and she hatched two of them!(She smashed the other one.)
