Can I put eggs under a broody that is on day 18

[CoopersCoppers]

I have a broody setting on eggs. She has a week left. I have other eggs that are in my bator that will be on day 18 tomorrow. Can I put the eggs under my broody instead of the hatcher. If so, will the broody continue her brood with the eggs that are due next week

I would think the eggs due to hatch later would get a lot of bacteria on them. Also my hen always has her chicks out the next day, if yours does the same she will have to leave eggs unattended, unless you pull the chicks.
