I am hoping someone may be able to assist with the sexing of my four 12 & 13 week old Bantam Australorps. I have read everything I possibly can on sexing them, but I find them all so similar I cannot tell. We were supposed to get from the breeder three females and one male. There are two (who I think are female), both 13 weeks and they are quite big, whereas the 12 week (female) and 13 week old (hopefully male) are still quite small. The one I suspect is a roo is just so friendly and curious I hope he is the roo, but he looks, to me, exactly the same as the others.
