I have always heard this is not possible, but I have one Pekin hen who has been on eggs for just over 3 weeks, and one who has been on for 10 days! Should I assume they will not 'follow through' with being good mommies(and steal the eggs to incubate elsewhere?) or give them the benefit of the doubt? They have thickly feathered nests, and puff up and hiss If I try to peek at them! My Muscovy hen (whom I only have to set eggs from the Pekins!) is enjoying the free life with the Pekin Drake now that he has no hens to followand shows no interest in setting (she sat on 3 clutchs straight last year!) How can this role reversal be explained, and what should I do? They are all in a large 70'x35' treed 'mini-orchard', have 2-3 small nesting houses, pools etc. I am worried they will start hatching and she will walk away... Help!
