How long can they sit?

[Quail27]

I have muscovy eggs. I got them in the mail the day before yesterday.
I have ducklings hatching in my incubators right now.
I was hoping to use my better incubators for the muscovy eggs, since those eggs are expensive.
In order to do this, the eggs might have to sit for 4 or so days after being shipped.

Is this going to be a huge problem? Should I put them in my lower quality incubators, risking complications from the incubator, or wait, risking complications from waiting?

I've left duck eggs sit for over a week before incubating and haven't had a problem with them. Of course, these were my own so I knew how "old" they were opposed to you buying eggs from someone else.
Why not start your eggs in the less desirable incubator and then move them to the more preferred one when it is ready for them? I would think that 4 or so days wouldn't be a problem whatsoever.
