Forgive me if there is already a thread/answer to this. I searched but couldn't actully find what I needed. Anyway, I have a mixed flock of ducks....runners, mallards and a pekin. My white rock chicken has gone broody on 5 duck eggs. I don't doubt that she can hatch them out, my concern is will they all hatch out at the same time or will she get confused if the hatch date varies? Will they all be 28 days? The eggs were layed yesterday and today. I will be blocking her and her nest off because she just keeps collecting eggs. I don't have a rooster so all the chicken eggs she keeps are of no good to her. If having a variety of duck eggs is no problem I'll leave them for her and see what happens. Is it a problem that she started setting on some yesterday and a few more today? And what should I expect for a hatch date or dates? Thanks for any input.
