Dome skull should be renamed empty skull, poor birds. Their lack of vision makes them helpless idiots, the big crested breeds.
That's so true but at the same time, I've seen some remarkable listening skills! My goofy polish cockerel has a crazy Crest and can't see anything but, he can hear that back garage door open from across the yard and will come running, full speed, up the step, around the door and up on the feed buckets to clean them up lol. He can't see much but you can tell he's listening when you talk to him. I love that goofy bird!
Good luck at the fair!
