I am getting ready... I have a hen that has been sitting on eggs... and they should hatch next weekend... about the 7th. I am getting a separate cage ready... and a light..... of course, I am in So. CA....
I am not worried about the mama hatching them, or keeping them warm for the first few days.... but, when they start to wander... then, what? So.. I am getting ready to keep them warm, at least at night.
(oh, by the way... I honestly think she went broody because we "stopped her broody" while I was worming -- had to stop her and were throwing all eggs away... so, she went broody again sooner due to that.... and her timing was Fall during the worming, and of course, Winter now, to make up for the last time, IMO.)
Good luck either way.
