Depending on the OP's setup, that could be a lot of hassle, though.I persnally wouldnt break her, but let her hatch them inside
I personally would prefer not to have an adult hen in my living room with her chicks, spreading dander everywhere. (I have allergies. Headache, blow nose every five minutes, sneeze my own throat raw allergies. Technically, they're 'mild.')
Of course, it's up to the OP, who knows her(?) own situation best. I'm just advising what would be the best course of action for me.
