I have 2 female pekin (nibbles & lulu) and 1 male black crested (sprout) ducks. The females are 19wks old and the male is 17wks. They have displayed mating habits with each other for the past month now, mostly with lulu, in the pool, by mounting her when he can. She embraces it. I never see nibbles being mounted, but that doesn't mean it hasn't happened. But I'm wondering when they will begin to lay eggs and if they do, what should I do with the eggs (in case they aren't being incubated by the ducks)? When will they begin nesting or making their nest? Will either female ever leave the nest to forage around on the ground and go swim?
