Incubating hatching duckling with chicken eggs

[Chickenlady386]

A friend of mine's duck was laying on a bunch of eggs and something happened to her, so I offered to have a really Broody hen help. One hatched but when I found it it was dead so I'm not sure if the hen killed it or what happened, but when I noticed another one was about to hatch I brought it inside. after 24 hours it hadn't made any progress and looked to be drying. My question is if I put it in my incubator which has chicken eggs on day three, would it harm the chicks in anyway? The temp hasn't risen much, but the humidity it at 70%. What should I do?

i doubt it would harm the chicks. if the one you found dead was out of the shell and bloody then the hen probably killed it

It was completely out of its shell, but not bloody. I think she accidentally smothered it

that can happen. i wish it didn't happen though!
