I've got 14 black australorps that I hatched 5 weeks ago. I thought I knew that the boys will get a spur on their ankle and the girls don't. But it seems that ALL of these birds have the spur. Is there another way to tell? about half of them have bright red combs. I know on most hens they dont turn red until they are ready to lay but I dont know if aurtralorps are the same. Any help is approciated.
