Please forgive me if this has already been addressed . . . I couldn't find it under past topics. My last two mother hens have pecked a few of their chicks to death and I was wondering why they do this? Do they know which ones are not theirs? They were not weak chicks, in fact all have been as big and healthy as their siblings. Is it because they were late-comers hatching several days after the others? Any light shed would be much appreciated.
