My Black Swedish duckling has some very interesting feather colors coming in. In addition to the black on her wings, she's also got green feather starting to come in. You can also see some green coloration on her face. I've got a Cayuga that's showing more green than she is but still, I didn't think I'd see any green colors on her at all! Is this normal? I'm not worried about her health, I just want to know if it's something that's a common trait in the breed. Thanks!
Green on her head under her eye
Green on the tips of her wings
