So I am new to the chicken thing and this is a one and only bird we have. My teenage son came home from the farm store with a chick. I am thinking about 15 -16 weeks old. I at first thought A female as I dont see longnpoint feathers in the neck region and no long curly tail in the saddle/tail. Does a lot of sitting but recently started to crow and become slightly more aggressive/ peck at us. However does a lot of clucking. Does have larger comb and wattle than other pictures I have seen but no more than 5 in the comb. I am finding black austrlorps are hard to sex in my research. From what I find combs and wattles vary in size in booth hen and cockrel, both can crow. Any help would be great.
