Well i just noticed Tahny has a thin chest bar as well!
She turns a year in about a week.
So what mutations cause females to have chest bars?
I would understand it if just Tahny had them, and it was a small amount like hers, but Falcon and Gus both have a whole thin bar that goes across their chest. and Gus has orange flecks in her cheeks..
Would it still be guessed as a /BB?
anyway, i tried to get as many good photos as possible, but she's a finch... I'll go to my neighbors house some time later and get pics of Gus and Falcon, because theirs are much more prominent then Tahny's.
