I believe it has happened. She's was on the nest all day yesterday, and again last night when I went to check on them. She was on it this morning too. NOW WHAT? It was pretty nice yesterday (high 50) but it got down to 25 last night. Supposed to start warming up gradually. I assume they'll be hatching here in about 3 weeks, if I can believe everything I read. They all free range during the day, but she lives in a coop with an Easter Egger, three banty hens and banty rooster and a MEAN Pheonix Roo. What happens if they do hatch. Will she take care of them? Do I need to build them a warm environment? Do I need to separate them from the rest of the flock? Need advice!
