Could this just be a batch of bad eggs? Maybe the chick the hen pecked was ill or not right somehow. I bought them from a local breeder, maybe I should get my next clutch somewhere else.
I candled the remaining eggs last night and one was moving around, so I'm hopeful this will hatch. Otherwise I'm 0 for 12
One last question, if the chick had died by smothering under the hen or something of that nature, would it be normal for her to have pecked it?
