Good morning everyone!
I brought a nice big pot of hot coffee for those in need.
With some other breeds I was not as successful, as it is a learning curve. Works best when you already own and know the ancestor birds for generations.

That's for the BCM since I started to determine their sex right after hatching or as one day old.So I imagine 100's of birds sexed as you described and only 2 were inaccurate?
That's pretty darn impressive, not something most could do.
