Hello, My beautiful red hen has just gone broody yesterday, she has never had fertile eggs of her own, she wanted "fluffy's" eggs (the silky) who I have just relocated. Anyhow there are some day old chicks for sale at the feed store. Is it safe to buy a few to place under her one night even though she has just gone broody?? or will she know they have "hatched" early. If it is safe I have to get some stuff together to make a ratproof pen.
