I have a broody Mallard. Since I don't have a Drake yet and she is the first broody I have decided to let her set chicken eggs. Now explaining that to my 8 year old granddaughter who is my chicken partner was another story. She said is she pregnant? I said no she will set on some eggs and hatch them. The little ones come from the eggs. She said like we eat and I said yes. She said is she going to have some baby ducks? I said no she will hatch some baby chickens. She said how? I said that we will put some hen eggs under her and she will set on them and keep them warm until they hatch. She said why don't we put some duck eggs under her? I said the duck eggs won't hatch. She said why? I said because we don't have any boy ducks. She said will the chicken eggs hatch. I said yes we have roosters. She said do the roosters hatch them? I said no they make the eggs so they will hatch. She said OHH? I think I left a puzzled little girl. But she is excited about her duck having baby chicks.
