Can I give my broody more chicks?

[CocoPopz]

She's a very good mum and current just has 3 chicks, they're now 9 weeks old and are going to their new home tomorrow, I would imagine she'll be upset, was just wondering how it's work if I put my 3 4 day old chicks there as a replace or will she kill them?

I do not think putting the little ones in will replace the ones going to a new home.
To her they will still be intruders.
