Hatching Guinea and chicken eggs toghter in same incubator?

[Krafty]

I'm thinking about trying my hand and some Guinea eggs but don't wanna tie up my incubator for a few Guinea eggs would like to add some of my Orpington eggs also. Besides the longer hatch time for guinea eggs. Should I stagger when I set the guinea eggs then a few days later add chicken eggs or can I set them at the same time?

Set the guineas first and then set the chicken eggs later so that they all hatch at the same time.
