Someone was asking me questions about ducks but I only raise chickens. They had 2 susies/ mallard. One died and the other is lonesome; they have had her hanging out with the chickens who pick on her. They have ordered some baby ducks. I know with chickens you can't put babies with older hens. Is the same true with ducks? At what age would it be safe to put them together? They say she is gentle with a nice temperament and the ducks and chickens will not be together. They got her in May. When do mallards normally lay? Are they seasonal layers? These folks live in Alaska so the days are geting shorter. Also I know how to sex older ducks by tail feather curl and also sometimes markings. Is there a way to sex them early? Thanks very much.
