Don't encounter many ground chicken dishes out in the wild at your typical restaurant, really, but I suppose that would still technically fit the bill! If it's on a bun, it's a burger, dammit!

Usually, though, it's either going to be a chicken patty of chemically separated and formed chicken (think chicken nuggets, but bigger) that's got a breading or batter on it and is deep-fried, or a less fake-y, more genuine hunk of chicken meat, often breast, thigh or a mix of breast and thigh, that's also breaded or battered and then deep-fried.
