I marked my eggs and just let her go. I've done this one other time, too. Just make her a little 'safe' place in the coop for her and her babies once they start moving around. I put a small dog crate with the door off for her to sit with her babies so they would be protected from the other birds. Once she got the knack of being a mommy she just pecked everyone and they just left the babies alone. This is what I'm going to do this time. My girl's eggies are due to hatch tomorrow, but one got broken on the large end and I brought it in. She is almost out of the shell this morning as I type. LOL
Good Luck!
