I put three healthy English Orpington chicks under my Araucana broody this morning before dawn and stole 2 of her eggs (and put them in the incubator). She raised a couple of babies in early February in the very cold part of winter. So far, so good, They are not screaming and she is all fluffed out over them. I helped the 4th chick out -- it had pipped at the wrong end about 24 hours ago -- I figure I had nothing to lose at this point. It rolled out ready to hatch and is fluffing in the incubator with the 2 breda eggs. It will join its hatchmates either late tonight or really early tomorrow morning. I'm hoping this works. I have no place for new hatchlings right now. I'm going to move them all into a cat carrier and put it in a pen inside the regular coop fairly soon to protect them from the rest of the flock.
