Hello and Welcome To BYC! Mountain Peeps gave you a good link to post pictures on to figure out what your girl is. A good side shot would help also to see her feather color better.
I agree with what all the others said. However, is she kind of hot? They droop their wings like that if they are. Again, Welcome and we are always happy to help!
If she has white she is red sex link, if she has no white she is a Production Red[or maybe a New Hampshire]. She's not quite dark enough to be a RIR, even a hatchery quality one.
Yes she was hot that day I looked up how to cool her down and she was great after that. She just showed up at my house one day. I never had a chicken so I have been trying to learn. But we love her and she loves us so now she is family!
