my leghorn is a roo? he/she is 9 weeks today. her watcha ma call it (having a brain fart) on top of her head is huge. all my other chicks don't have combs yet. all same age but each a different breed. could she be a roo ir do leghorns just mature real fast? when should i expect to know if she's a he? and if she IS a he, when can he go to freezer camp? i can't have any roos. i'd put a pic on but for some reason i can't. any help would be great. thanks
