i don't breed them, though they have bred for me... i have a male Roller and two male American Singers.... i had a female AS and another female mix of some sort which looked a bit Norwich... due to space issues and the amount of feather dust in my apartment (i have 3 other birds, a fiance and our daughter-plus all the tanks) i had to find other homes for the girls. i miss them, but i know where they are and they are in good hands.
I can't find timbrados locally or i'd likely have one by now
I love them, they sing constantly, all three at once....what a beautiful racket!
