ok, I did read the posting if right forum thread, think the short discription idea would help , In my opinion, this is where I would put this, because for me it is a managing issue. Or maybe need a Husbandry section,lol or did I miss it. Have a production Red rooster to best of my knowledge. I have some big wide body white hens, that I want to breed later with what is looking to be a Black aussie Roo. Just want to get a good time frame for seperating the hens I want to breed to aussie from flock with PR Roo so I know I have at least a 90% chance it will be aussie.
