You can go and mark the ones that are in there with the date, then mark any new ones laid with the date layed. Then I would leave them in there for up to 2 weeks to see if she will set. If, after 10-14 days, she still hasn't went broody take the oldest eggs out of the nest. You can use fine grained sand paper to get the worst dry stuff off, others have said they use very warm water, run the egg under it, and wipe dry. I don't do this personally, so I don't know how well it would work or if it would affect them.
Rouens are not supposed to be broody birds, but there are many people on here that have broody rouens and pekins.
