How can you tell if your chick is male or female?

Male convicts are just grey and black. Females Have a bright orange color in the belly area along with the normal black and grey coloration.

males are typically larger than females and are just a black and grey colour. females are smaller, and i think are more pretty since they have more colour on them. they are black and grey, but they also have orange on their belly and they can also have bits of blue, green and yellow on them.
