I would not be comfortable until she laid out or 7 eggs.

When I change roos I allow 4 weeks.

From what I've read, the hen can have sperm stored from the old roo for up to a month.

I would presume they would mix. Then you would not be sure which roo is the sire of any particular egg laid. To be sure that the second roo is the only one fathering the chicks, you would need to wait a month.
