If you let muscovy hens or a domestic goose raise your swan babies, will they be more inclined to use a house (or the house that they were raised in) to lay and set eggs? Also, will they come back to this house at night? One more question. If the cygnets are raised by the duck hens/geese, will they accept the other ducks and geese as their flock? I'm hoping I can keep my future ducks, pilgrim geese, and swans all on the same pond.
