My "Avatar" is setting on 12 RIW eggs, she shares a pen with 4 DLW, 3BLW, 2SLW. My husband can build me a cage for her to be in closer to hatching, I would like to keep her in there so she can raise the chicks, what would you recommend for a brooding box. And how long should I keep her in there, the Wyandottes are very friendly, but still, I would hate to lose a chick unnecessarily, any ideas. She will hatch them two weeks from Friday.
