My 10-year-old son bought a couple chickens back in August. One is a Buff Orpington and we have no idea what gender this chicken is! It has a small comb and wattle. It hangs out with our rooster all the time and we see them fight. Its very bossy. Its obviously big enough to crow but no crow and no eggs. It lets my kids pick it up. Doesn't fight them. Its about 6 months old I believe. Its also a very large chicken.
