If I had it to do over again, I would have separated my broody much sooner in the process. I would have given her a space to herself, with closer access to food and water, and warmer temperatures. It was the first time for both of us, and we made a mess of things in some ways. Beyond the problems generated by having a chicken in the spare room for any reason, I have a dog in the house that is a danger to my chickens, and it takes some real extra effort to ensure their safety in the house, too. Still, it has worked best for the health and well-being of my hen and the babies. I wish I would have done it sooner.
I have so many plans for improving the chicken house this spring from all this . . .
Oh, I'm sorry to hear that your first time didn't work out so well! It'll work out better next time, though!
