So lets say i'm incubating 8 eggs. Developing nicely insidemy nice little incubator. Its day nineteen and soon they will hatch. In my chicken coop is a silkie momma going broody. So my question is, would it be possible to put those theoretical eggs under my theoretical silkie the last few days before they hatch so that the theoretical silkie will raise these theoretical chicks? Or will she figure out that it takes a little longer than a day or two to hatch and won't accept them when they do hatch. As you have probably figured out, this question is purely theoretical. Well, to an extent. I have recently bought an incubator and i do have a few silkies but there only 3 months old so they won't be going broody soon i expect. I mean it sounds like it would work but things have a funny way of screwing up sometimes so i thought i'd consult my intelligent friends at BYC.
