I gave six Muscovy hens sitting eggs in my yard. This is my 5th year raising Scovies but this is the first time I have had hens switch nests a week before hatching is due. I picked up the hens and placed them on their corrects nests but within an hour they had switched again. This is the 3rd day of them sitting on the wrong nests. Will they reject the ducklings that are not from their nests or does it matter which nest they hatch??
