I do this often with good success however if she is JUST now starting to be broody and it's only a week or so to the egg hatching, she may not accept them. I have one hen that will accept anything at day 1, but my others seem to need at least two weeks sitting before they will take chicks. If she's just now broody, I'd opt for caution - you could hatch the chicks and put one under her at night to see if she'll accept it, but be ready to snatch it back if she's not ready.I think I've got a broody hen on my hands. I have some eggs that are due to hatch next week. Should I let her have a few? Honestly, I would like to open up some room in the incubator to put Isabel's eggs in. In the mean time, I am testing her dedication by putting a couple of wooden eggs under her.
