I have 2 broody hens, 1 decided to bury herself in the hay loft and hide her eggs from me. She is laying on 2 duck eggs and 1 rotten chicken egg, I candled the eggs and they're about 4-5 days along. My mallard always goes broody around this time, but a new mate is distracting her, she literally goes a mile down our creek, which she has never done. Anyways, my father does NOT want a chicken hatching out duck eggs and if he found out what happened he would throw them out and I don't exactly want to kill a developing duck. Is there a way to encourage my mallard, or for sakes my crested duck (She's also gone broody, she's just a horrible mom) to go broody? within days if possible? Anything helps, thanks.
