More than one mother?

[MicMoo]

One of my hens (I have three) went broody for the umpteenth time about two weeks ago. Since I don't have a rooster, I decided to go on Craigslist and find some fertile eggs for her to set on. Now two weeks later ALL THREE of my hens are broody and squeezing into the nesting box all trying to hatch the eggs.

Would it be OK to let all three of them stick around as mothers or would it be better to move two into another coop and leave just one to brood for the last few days and then play mother afterwards?

I'd seperate one hen and the eggs then either break the other two or get them eggs of their own to hatch. I know people have had co-broodies be succesfull, but I think there is too great of a chance for broken eggs and smothered chicks with three hens crammed into one box.
