my BO hatched a couple this last October and she did great. we had a few mishaps this being mine and hers first time hatching eggs. She did great especially when I got her seperated by the rest of the flock. I used a wire dog kenel in the coop. She was still seeing the flock but they couldn't get to her nest and I just placed food and water inside with her. I had to do it this way cause I only have one coop. She didn't have any issues with the babies once they started hatching, she was very protective of them, even pecked me a few times while I tried to look on. We did loose a couple, I found them out of their shell but no long with us, I believe they just got smothered but no way to tell for sure. The kenel worked great because they still had some interaction with the rest of the flock but were secure at the same time. When they were finally let out with everybody By Bo did great the flock was out free ranging and she kept to the pen for the first week or so then she free ranged too. She just kept the babies away from everyone till they were older, and kept to the brush more then everyone else. But it was great watching her teach the babies how to scratch and chase bugs. She even defended her babies from the out side kitties that were just passing by. And since it is wintertime anyway and wouldn't be laying she mothered them for ages, they were 12 weeks and she was still sleeping with them but now she's laying again and left the babies to their own devices. About time too since they'er bigger than she is, and just my luck both roo's.
Oh and I don't have a clue as to whose eggs she actually hatched either.
