What options are there for her parents? SHe appears to have inherited dominant white, a gene not commonly found in silkies, so I would guess that her non-silkie parent carries it.
she was with our house when we bought it and sleeps up in a tree at night. we don't feed her or anything, she just hangs around doing her own thing. we think she might be about 13 years old. so I don't know anything about her parents. I will try and get more photos of her.
