We have a caguya duck, Pepper. For the longest time she just laid her eggs anywhere in the yard and left them. She started going missing and would only return for feeding time. I finally found her. She built a nest and had 11 eggs. Because our drake had been killed by a hawk I knew they weren’t fertile so when she left to eat I replaced some of her eggs with fertile chicken eggs. Our chickens don’t sit on their eggs so I’ve been hatching them in an incubator. Will Pepper be able to hatch the chicken eggs? Will she claim them as her babies if they hatch? She is also vicious now. She’ll start hissing and try to bite your hand off if you try to touch her best. She is very seeet when she’s away from her nest. Is this normal?
