My MIL has ducks and recently one of them laid an egg. She thought the duck(whichever one it was) abandoned it b/c she never saw a duck sitting on it so she asked me to put it in with my chicken eggs that has a broody sitting on them. I warned her that I didn't know how the chickens would react to it being in there but she insisted, lol. Anyways, I looked around a little bit ago and found a nest with 2 eggs. Now, my question is, can the egg that was put in with the chicken eggs be taken out and put with the other 2 duck eggs? Or should I just leave it with my broody hen and her eggs?
