I have a broody hen here, (mid-west USA) and cold winter fast approaches. I have heard of chicken keepers buying chicks and hiding them under a broody, and she accepts them, thinking they came from her eggs. I just saw that my local feed store is selling 2-4 week old chicks. I was wondering, if I got some two week olds, could I hide them under this mama? Would she accept them as her own, or are these babies too old for that at this point? Thanks for your input!!
