I am new to this site and hope someone can help me. My chickens are about 18 wks old and i think they are all hens but my boyfriend thinks we have 2 roosters because there comb and waddles are larger. Not a one is crowing or laying yet. I am getting there nesting boxes ready today and hopefully they will be laying soon. But if i have 2 roosters will its tail always be bigger, do only roosters have the spurs on there legs, and dont chickens have karge waddles and combs when they are ready to lay?
