First off, I'm new to chickens. We haven't had ours a year yet but we're loving them! One of our hens went broody and she hatched her four eggs just a couple weeks ago. Three survived and are doing great. My question is about how long the chicks need to sleep under her at night in a nesting box. As of yesterday evening the chicks have been going up on the roost with her and are sitting under her on the roost! Yesterday we thought the chicks had disappeared until we looked up and saw all three up on the highest roost with mom- it's probably 7 ft off the ground. I was shocked! We've taken mom and chicks down each night and put them all in a nesting box because I'm not sure if this is really safe for her and the chicks. I've tried to let them alone and let mama do her thing but should I keep intervening here?
