Mixed eggs

[Rubberducky3]

Someone gave my 3 duck eggs and a chicken egg to hatch. Can these be done in the same incubator? I know ducks take longer

They can, if you put the duck eggs in for a week and then add the chicken egg after a week has passed. Depending on how old the chicken egg is, it might not be viable at that point, however. If it's freshly laid it shouldn't be a problem.
