I will let them have the nest they have chose, then close to hatch day I take them nest box and all out to the broody coop and tuck them in for the hatch , I use to leave them inside the coop through the whole process but have you ever had 3-4 hens with chicks trying to get outside in the morning? not a pretty site. not here anyway. lol I also had another house that I used for broodies too but it has become a goose house so these girls are going to have to wait their turns this year, only 2 broodies at a time. lol
I'm with you - I much prefer to see my broody hanging out in the nest box all day then to see the in/out of the layers. LOL! I would love to have a dedicated broody hutch and hope to make that happen in the next year or so. We shall see. My Topsy did fine this past time hatching her babies out in the nest and getting them down out of the nest when it was time.
