I would leave her in the coop. All my hens hatch out in the coop. No one bothers them, they may lay when she gets up, but you can remove those. Or you can get a dog kennel and put it in your coop. All of my hens have their babies out on day two of the hatch. They are in with the others so there is no integration issues. I have two hens out in my coop now with 2 roosters and 10 hens and 4 teens, between the two hens they have 18 chicks no one bothers them. They learn where all buggy honey holes are. It is a watching a mom try to watch over 12 chicks. She is doing a great job. The Marans has 6 and is doing fantastic job also. It is a blast to watch, they don't let anyone to close, unless they trust them. Have fun give her a few. I wouldn't move her.
This sounds soooo cute! I can't wait.
