How many eggs should I place?

[shishimarie]

Hello chicken friends

I have a broody Orpington and I’m going to place a clutch of eggs under her. I am getting 10 eggs and they all will be Orpington eggs. So my question to y’all is how many can I place under her?
She did sit on a clutch earlier this summer but it was a mix of eggs. That time I placed 7 under her (2 silkie, 2 Easter Eggers, 2 cream legbar, and 1 barred rock). on day 10 when I candlelighted them and all but 1 (cream legbar) was developing. The remains 6 did all hatch but 2 chicks did not survive.
Thanks for any comments

I would put all 10 then go out half an hour later if any are pushed out put them in an incubator
