Call Duck eggs

[Bushy T]

Hello I'm new to call ducks and hatching eggs. I bought some eggs for one of my call hens and then she stopped setting

so I put them in my incubator and they are on day 9 and now one of my other call ducks went setting on 1 little tiny egg should I or could I set the eggs under her and let her set for the rest of the time or will that mess up my eggs.
