I have a chicken that's 3 months old and is a Hamburg I and not a new person with chickens I have a flock of 5 that's 6 years old and a flock of 9 that's 4 months old then 3 small chickens that are 3 months old and I have never kept this type of breed so im only new to the breed I show my chickens and use them for eggs so I wasn't sure what gender my chicken is because the chicken I named it caramel so any way caramel has some green in his black and brown coloring and I know a black Australorp (I have this breed) has green kind of coloring in it but its in females and males but roosters have that too and Hamburg's have a big tail but I don't know because roosters have big tails also this chicken I have also has green in its tail which roosters have and a big tail which I know the breed is but im still deciding whether its a male or female so I need some opinions
