Can 2 broodies be in same pen if one has a chick and one doesn't yet?

[chickngranny]

I have one Black Australorp that has a 2 day old chick and still has another egg to hatch probably today. I have another BA that is now broody in the coop with the rest of the flock. I move my broody hens to a 10x10 pen in our barn so the other chickens won't bother them and the chicks. Is it ok to bring in this other broody with some eggs and her own box since there is a new chick and hopefully a second due to hatch? I don't want this to cause a problem between these hens!
