I have two drakes and two ducks that I bought as babies last spring. One pair are "tuxedo" ducks (black with white bibs) And the other are not. One male is a blue splash, and the other female is brown with a white bib. (I don't know what breed they are). I also have a goose in the pen with them. She gets along with them fine. My question is, the males have already been exhibiting "mating" Behaviors. Should I be expecting eggs any time soon?
