I'm no expert; I've never had a broody hen, etc. But I'm inclined to let nature take its course. If she starts eating it, then I would start worrying, but meanwhile, I would just watch and wait. Sorry, I don't think I'm being much help.
I hope someone else gives you more experienced advice!!!

My first chicken is broody.... Just ordered 6eggs for her! She is a buckeye, hoping to be mama to BLRW +plus maybe a few of my own crosses!
Yay!!!
