Austra White is a good guess! However, her comb is too small. I would guess she is over 20 weeks and is some kind of cross, perhaps with some OEG in there. Her comb is just too bright to be younger than 15 weeks.
Here's another pic. Any other opinions? She's friendly but feisty and gets restless when first placed in run or coop. She's accepting her new friend slowly, she still intimidates her but they roosted side by side last night.
