Thanks for posting pics. I know this is your first try. I can't see too well some of the characteristics of your bird in those pics, but it looks kind of like a brown leghorn. The only problem is that brow leghorns lay white eggs.
So I'm not sure if it's some kind of a cross. Hope others can give more imput.
The coloration is similar to a brown leghorn, but the head and face don't look like anything I am familiar with. I hope others will be able to provide more insight.
The head, eye and comb make her look like a game bird of some kind. For reference look at the shamos or aseels in the breed section. That's some beautiful feather color she's got, but it's certainly not GLW.
Hard to say for sure, but feather pattern, head shape, and over-all stature lead me to believe there is game in the background. She also looks to be very tight feathered?
