The chick was dead this morning as I suspected it would be. The second one is doing great, though. Fortunately I have a Black Copper Marans chick that did not sell with the others because it was not on its feet at the time the buyer picked up the rest of the chicks. I am glad I held it back or I would have a lonely Barnevelder chick and the BC' chick may not have survived since the one hatched at the same time that seemed stronger ended up dying shortly after it left here.
The woman I bought the eggs from told me that her Barnevelder rooster is related to two or three of her five hens. That would explain the large number of unhatched and dead chicks. She gave me some more eggs to hatch so I will assume that anything that lives is out of the two unrelated hens. I suggested she get a new rooster in order to have viable eggs for hatching. I don't want to go through the high mortality again but at least now I know to expect a poor hatch from the eggs due this weekend and from the eggs I need to put in the incubator.
