I have two broodies who went broody around Sept 1. Their eggs should hatch around the 21st, 15 in all may hatch. I have safe, enclosed brooding and run areas for them both, separated, but I'm wondering with so many chicks developing -bantam cochins- will they be able to cover them all to keep them warm? The nights will probably dip down to 40 the first couple weeks of life, maybe down to freezing by mid-October. Should I consider having brooding quarters inside for nights under 40 F, or no worries about temperatures? Days will be in the 60s& 70s mostly, with a few rainy days in the 50s I imagine. This is S.W. Pennsylvania. Should I consider leaving 4-5 with each hen & raising the rest in a brooder? I've got that down to a science. It's the mama hens I don't understand vry well. Does anyone have any wisdom to share? All my other chicks hatched out when it was much warmer, and there were no cold concerns. There also were far fewer chicks.
