I think it's more the incubator and the hatcher I have. Get hatches like this all the time. Not sure about the 18 in the other tray. There eggs I got from a friend. He said some might be a bit old. I see about 3 or 4 eggs that haven't hatched yet. Looks like all the marans hatched but the ameraucanas not so good.Even if you have to cull it, a 100% hatch is awesome!!! BR's seem to be easy to hatch...![]()
