Sounds more like a rat or weasel. Yhey will slip under a hen and grab a chick in a heartbeat. No shortage of rats here in Oregon. Tam'ra of Rainbow Vortex : Yesterday, my broody silver penciled wyandotte hatched out a darling little grey-brown mutt chick. I was delighted since my dominant roo is black and I always want more colors... I was so excited to see how it would turn out. But today its decapitated body was found with its mother in the nesting box with the four other unhatched eggs she sat on and one new egg laid by another hen. She must have left the nest for that other egg to appear. So what do you think? What is she guilty of- criminal negligence or murder? I will not be keeping this hen. If I had known she would not care for it I would have slipped it under my gold laced broody.
