That's kind of what I was thinking, Boggy. (Glad you chimed in. I have been drooling over your lav. cuckoo birds.)
The autosexing trait is important to me. It's unfortunate it's not reliable with this variety, it is a gorgeous color.
So how well does the auto-sexing show up on teh lavender birds? I was afraid the color would be so light on chicks that it would not be very accurate. Can anybody produce chick pictures of lavender cuckoo males and females? I searched, but couldn't find any of any breed.
