Thanks GaryDean. I have the same diagram in a book with a page and a half discussion on autosex, but was unsure of posting (copyright). The pictures of the roos, especially helpful. Got a nice little thunderstorm pass through here. Still haven't rebanded. Chicks/ juvs now spending their days outside learning the world and how to retreat to the baby coop. At nearly 6 weeks, they haven't spent the night out, but we're getting there. Boy will I miss the fun of round up time!! Definitely prefer a broody hen!
