Well, I know I can narrow it down by one as we have one roo who has an asymetrical face. I can't quite decide if he is crossbeaked. I noticed a while back that his comb didn't run straight, my daughter commented that one eye is crooked, and after closer inspection, his entire face looks twisted. He's a sweetie to us, but does want to be dominate with the boys. We have a soft spot for odd balls, so he will probably be staying as long as he is healthy and eating well.Yes, it's quite the undertaking! LOL
