I am SOOO new to chickens and especially to broody hens hatching. So, we just had our first chick hatch sometimes in the last 12 hours. Mama is in the coop, in a wire dog crate and it is pretty cool out. High 50ish and low 27. I have a heavy blanket over her cage. Will this be enough? I do NOT need to provide light, correct? I would like things to be as natural as possible. What is the best age to let them out of the cage with mama and let her guide them? Will she keep them from going outside when it is so cool out? Thanks for any help!
