You need to post one of her from the side, we can't tell much from the front, especially when it's not right side up.
But I can already tell you she doesn't seem to have great spots( not enough, and not spread out evenly but she may get more later), her feet feathers are too light and not in good condition (she'd have to be on shavings 24/7)
If you can find a copy of the APA standards book, you can compare her to that. If you are showing for 4h or county fairs, go for it as most of those are on showmanship and so on and are loose with the rules. However, for a "real" show, you probably want to get show quality stock. Meaning, unlikly any hatchery or back yard bird you get for 4 bucks will cut it.
