These are my first ever chickens. I got these three when they were 3 days old. They are now 8.5 weeks. To my untrained eye the middle one looks like a cockerel and the other two look like pullets. I'm not allowed roosters where I live so if it is a cockerel I'll have to find a nice home for it. Should I wait before finding a new home or is it almost definitely a cockerel?
