I'm jumping in on this thread to ask a similar question since this is fairly recent. Our puppy stole a mallard egg from a nest along our property. My daughter managed to get it away from her without it cracking or anything. Then she looked around for the nest but couldn't find it. I candled it and nothing had started to grow yet, I assume the duck just started laying and not sitting on the nest yet. Anyway, my daughter begged me to put it in the incubator with the chicken eggs I had in there... So without really thinking too much about it I obliged. Couldn't stand the thought of just tossing it... A few days later I candled it and, sure enough, it's growing. I had the thought that maybe I could pass it off to a mother duck if I see one with ducklings, but will she accept it if it didn't hatch in her nest? Also, I found another egg the next day that was already eaten by our puppy. I'm not sure the mother will actually stick around if her eggs keep getting stolen. So IF the duckling actually hatches, what should I do with it? My daughter is quite convinced she will be having a pet mallard, but I'm pretty sure it's not really allowed. (I'm in Canada) Though would it really matter if I let it out on our dugout eventually and it found wild friends and followed them? Sorry lots of questions!!
