Hi all. I have 4 eleven (11) week old birds, all different breeds, and one is definately not like the others. I've been scouring the web for answers, but nothing has me 100% certain. He/she is a black Australorp (I think), and has a very large, red comb, big waddles, and is significantly larger (leg size, height) than his/her sisters. It makes a sound (not entirely a cock-a-doodle-doo) loudly some mornings, some afternoons. Any advice on the gender? I'd love it if it were a she, for she's the sweetest one of the bunch. Thanks for any input you may have.
