Does anyone on BYC breed partridge rock bantams? My son has a little rooster and he is so very tiny. I would love to eventually buy hatching eggs to build a small flock. This is the sweetest rooster, ever. He is so much like a little puppy dog. All the other chickens hate poor Chocolate, lol. He is fully feathered and almost 4 months old. When will he get his colorful adult plumage?
