lockdown eggs under a broody?

[Vanessabuffsnsilkies]

I have 3 broodies sitting on eggs. 2 due about the same time, only one hen has 2 eggs, the other has 4. So, I have 3 eggs in the bator going into lockdown tomorrow. Would it work to move eggs around and put the lockdown eggs under the broody? I know you can put newly hatched chicks under one...

The only reason I would figure it not working out so well for you is if their hatch date is different than the incubator eggs hatch date. If it's off by even a day there's a chance the broodies will abandon perfectly good eggs to take the already hatched ones out for a walk, and that's no good. But if they're all set to hatch the same day, I don't see why you couldn't slip them in overnight and let her hatch them out.
