Working on that -- didn't upload the first time. Since I'm re-posting, I am wondering if anyone knows if the auto-sexing traits disappear at a certian age between hatching and adulthood and if there is a period of time when they are unsexable. I'm asking because the roos seem, in some cases to be losing their light spots as they feather out.
so so so cute!! awww

Based on my experience, the autosexing is always evident as the males become increasingly barred and the females develop the typical female Cream Legbar plumage pattern. up to bout 12-weeks the males are barred mostly black and white.
