I have 5 female ducks (and 2 ganders). They are about 20 weeks old and one of them is laying for about 2 weeks now. I build them 2 nesting boxes but so far every morning the eggs was waiting for me in the middle of the coop on the floor. I know that the ducks check out the nesting boxes because every day the fake eggs I put in it to encourage them laying in there were pushed around and under the hay. Ugghh!!!!! Almost gave up but today for the first time I found the egg in the nesting box!!!!!!! WOOHOO!!!!!! So excited ………….now if only the other ones will start laying soon and IN the nesting box that would be awesome. We are really enjoying those yummy eggs!
