Our ducks (1 pekin, 1 Cuyoga, 1 magpie, and 1 rauen) are starting to lay eggs, I'm not sure who's actually laying and who's not, we just randomly find larger sized white eggs in their pens. The only male duck we have is a Rauen though. Can he fertilize the eggs of the other breeds? We OFTEN see him breeding the magpie and the female rauen, and occasionally the pekin. However, NONE of them EVER sit on their eggs or the 'nest' they sometimes lay them in. They dont have an established 'nest' like chickens or even some other ducks, they just randomly lay them in different places, then leave them. I'm not sure if they'll hatch because of the breed difference, and not sure what to do about them not 'sitting' on their eggs. Can anyone tell me anything about how to fix this or if they will even hatch with the breed difference? The pekin is around 18 mos old, so is the male rauen, the cuyoga female is around a year, and the other 2 were born in april of this year.
