My "sister wives" - leave them in the same nest box, or separate them?

[chics in the sun]

Well, Ginger the olive egger went broody a week ago. I decided to let her hatch out some eggs, and today I found her half-sister, Sky the Ameraucana, keeping her company in her broody-hood. Here they are:

As you can see, the nest box is fairly large and they fit in there together pretty well. I have won a total of 14 eggs, and wanted to put 7 under each. So should I try and put one in the other box, or let them sit together? I can block off where they are fairly easily. I also have a brooder with a nest box that is too small for both of them. Advice?

My advice? Go mark the eggs she is sitting on. STAT! The other bird is in there to shove her eggs under the broody. You will wind up with eggs that are sat on coming out and newer ones being pushed under from behind. Check her next every day and remove the unmarked eggs.

I had 2 or 3 that would steal eachothers eggs over and over. one day 1 would have a bunch under her, and the other would have 3-4, the next day total opposite.

I thought that at first, but she has been just sitting next to her, all puffed up and making teradactyl noises when I get near for two days now (even at night). Neither one is actually on viable eggs yet - they are being mailed to me today, so I am trying to figure out what to do before the hatching eggs get here. I have no rooster, so any eggs that get stuck under them will just sit there and go bad.
