I have a broody cayuga duck, right now she's sitting on unfertilzed eggs. Now my question is, can I put chicken eggs under her? Or would it be better to get duck eggs. Also, she has her nest right in the middle of the coop, I would like to move it but she is very nervous and when she see's me she gets up off the nest and goes outside and then comes back and sits on them. How could I move the nest without making her leave it?
