I have a Houdan hen who went broody at the end of June. She has stopped laying and sits on everyone else's eggs. spends most of her day in the nestbox, but does get out a bit with the others. She is a bit on the thin side, but not desperately so and she does eat & drink from the regular feeder & waterbowl. This weekend I will be visiting a friend who has chickens. She has crossed some Isa Browns & Wyandottes - she calls "Isa-dottes" - and has offered me either fertile eggs or chicks from this cross. If I took day-old or not much older chicks what are the chances my Houdan would raise them? I'll be coming home Sunday before dark and could sneak the chicks under her that night when all go in to roost. Or, I could mark the fertile eggs and slip them under her. I do not have anywhere I could isolate her with the chicks unless I close off the door from the coop to the connecting fenced yard and leave them out side. Right now temps are plenty warm even at night and I could put a cat carrier in there for a nest & some shelter. Does any of this sound like it could work?
