So, I got my 3 Buff Orpingtons as chicks in October. They are just over two months old now. I have worried all along that one of them was a rooster, because he/she is much bigger and more aggressive. People at the Feed store told me I wouldn't be able to tell for a couple more months/until they tried to crow. Well, the chicken in question just let out two loud squacks while flapping its wings and stretching its neck out. Is this the nail in the coffin? Or should I wait it out? Here is a picture of the three chickens (dressed up for Christmas) ... I'll let you guess which one I think is a rooster.
