Hello there and welcome to BYC! 
Oh poor thing! Do your best to lure it in, chickens are not easy to catch. You are not alone, another new member just had the same issue and did eventually catch this rooster in a crate with food in it, (a cinnamon roll of all things.

So glad you're here, and talking to fellow chicken lovers. Hopefully you can already see everyone is concerned and offering advice. So if you do manage to get her, folks here will be more than happy to help you figure out where to proceed.)
I hope she will stay safe! So many wild animals out there....
Thank you for the help everyone!
