i slipped some chicks under a broody hen and they've been doing great. They are 3 weeks old today and I live in Western WA. I set them up in a horse trough for the brooder and they started jumping out last week. Tonight I found 2 of the chicks in the brooder and one up on the roost with the mama. Do I just allow this and assume they know best? Or do I go out and put the stray baby and mama back in the brooder? I've let them roam about with mamahen during the day and they seem to be doing well.
