What breed is she?

[PicketFarmer]

We recently caught a stray chicken that's been hanging around our yard from the other side of the fence for at least a month. At first, she would just pace the fence and chat with our girls. Occasionally, she would hop the fence and stand outside our chicken yard, squawking to be let in, but would always run away whenever we got too close. Recently, she finally worked up the courage to start running up the hill with our girls when we let them out to free range, but still ran away whenever we would get too close. Until today, when she decided to wander into our chickens' yard through the open gate, where we closed her in and finally managed to catch her.
We have her isolated in a small run/coop that we use for introducing new girls to the flock, while we wait to see if anyone is missing her (doubtful, since she's been missing for at least a month, and I haven't seen anything about it); if not, I'd like to try to get her used to humans again - she's very skittish and nervous around us, though she calms down if I manage to catch and hold her - and introduce her to the flock officially once I'm sure she's not sick and contagious.

But whatever the outcome, I'd like to know what breed she is. As you can see in the pics, she's a buff color with black markings and tan/bronze hackles, a single comb, and greenish-grey legs. Based on my research, the only breeds with that color legs are Araucanas/Ameracaunas, Easter Egger hybrids, or the extremely rare Green-legged Partridge. Since I'm pretty sure she's not on the endangered list, my best guess would be an Easter Egger x buff Leghorn hybrid; if it wasn't for the green legs, I would say pure buff Leghorn, but the unique coloring is throwing me off, so I thought I'd ask here for a second opinion. Any suggestions or guesses would be welcome.

P.S. Sorry for the bad angles. She's still skittish and runs if I get too close.

Beautiful American Game Hen. Looks like a Pumpkin.

Huh, I didn't see game hens in my search for green-legged chickens, but after looking it up, the hatch and/or pumpkin hulsey is definitely what she looks like. She's definitely a pretty girl, and Pumpkin would be a great name for her if we end up keeping her.
This would be the first game hen I've raised - we have an old, retired flock of barred rocks and brahmas, and a young, new flock of black copper marans, anconas, and buff orpingtons that just started laying. Are there any special considerations I should take in handling her different from other breeds, or are game fowl similar to most other breeds? All I know about her right now is that she's a flier - I watched her catch 10 feet of air off the ground to roost in the trees one night - skittish, but also curious and relatively calm when she doesn't feel threatened.
Also, any idea how old she could be? My initial guess was around 3 months, but that was based on my assumption that she's a large breed that would get bigger; if she's a small or medium breed like a game hen or EE, I'm not sure how to tell aside from whether she's started laying, yet.
