Hello! I have a broody hen who is sitting on infertile eggs (we have no rooster.) I found someone who sells fertile eggs so I thought I would try and put them under her. (I can't have roosters where i live but the fertile egg seller says he will take roosters back! YAY!) Anyway, may be a stupid question, but are the little chicks safe 3 feet up in the nesting box? How does the hen deal with that? Thanks.
