When we bought our 3 chickens from the local feed store, we bought one of each type that was available. 1 Buff Orpington. 1 Barred Rock, and 1 Americuana. As a chic the Orpington was a yellowish fluff ball, gradually it turned completely white. The man at the feed store thought it would change to buff after it matured but now at 6 mos and laying she is a large pure white chicken. The weird part is she is layig blue/green eggs???! SOOOO what could she be? I have looked on a chart but didnt find a white chicken that lays colored eggs. She has olive green legs w/ cream color toe nails, brown eyes, and is a LARGE chicken for 6 mos, compared to the Americauna.
