I saw an add online from the same lady that I bought my Fallow chick from. She made it sound like she had another one, so I jumped in my car and headed over. turns out it was just a regular pied with dark plum eyes.
While I was there though, I came across this beauty! And since I don't have any blue in my aviary, I couldn't go home without it. The lighting that she had wasn't the greatest, so it looked like a male. Under my lights though, it looks female.
My husband has named her/him Turbo
My mutation guess is Sky Blue, Yellowface II Greywing.
