Thanks for starting this thread. I just gave my broody fertilized eggs for the frist time yesterday. This will be my very first hatch. Should I remove mom and babies at first and put them back in the coop at 3 weeks? Or leave them out the whole time? I am so nervous!

Did you get a picture of that? I never had my camera handy when my barred rock did this. She would have half of the chicks (21) up on the roost, between her legs and under her wings. It was so cute I could cry! She started this at 2 weeks. I had a ladder up on the roost for some juveniles to easily access the roost, and the 2 week old chicks had no problem!
