So I've reintroduced my two babies to each other (they were being raised by kids in different homes) and they've joined my hens in the coop. I had to divide the coop for now as the older hens weren't too excited about sharing with the little ones. Anyway... my chicks (now about 6weeks) are supposed to be pullets - one aracauna and one black australorp. I'm beginning to become suspicious of the black one though. Her crown & waddle are MUCH more pronounced than my aracaunas is - though I know that can vary... my buff rock has a very small crown while my barred one has a huge one. But it's more her behavior that has me worried. She's quite dominant and active. She picks on the americauna, chasing her, nipping at her, etc. She doesn't seem to be hurting her... just scaring her. It's not constant... but it's enough that the aracauna generally keeps her distance. I'm wondering... I know the australorps get GORGEOUS as roos... when will I notice anything that could tell me for sure she's a hen (or not)? There was a white cockerel mixed in with my adult hens when I got them (he was supposed to also be a hen) and I wasn't positive (but again, the behavior was the clue... active and dominant) until he started trying to mount my hens. Will I be able to tell sooner with the australorp?? I really hope she's a girl... I warned the kids that if one of them "turned into" a roo it would have to go elsewhere (we live in the city, and I don't want fertile eggs anyway)... but it will still be a tough time. Any help confirming HER (knock on wood) sex would be AWESOME!
