My friend has some cute little ducks she calls them call ducks. I can't find much on call ducks so I have some questions. 1) are call ducks bantam ducks? 2) How big do they get 3) are they friendly? 4) do you incubate their eggs like chicken eggs? 5) how messy are they? 6) do they have to be under lights like baby chicks? how long? 7) are call ducks easy to care for? & in winter? Anyway, anything you can tell me about them would be great. Are there any good books that are strictly about call ducks? Thanks!
