After 4 years of having chickens I finally had a mother hen hatch out 9 beautiful babies....right in the middle of winter. I have them in my basement in a open wired dog crate. We are in NC so I'm not using a heat lamp just depending on Mama for heat for her babies. Just wondering if the experts could tell me when I should try taking them all outside or should I separate the Mama from the babies? Any advice would be much appreciated.
