I'm glad you enjoyed your visit Jimmy, there are some very nice fancy pigeons out there and some of them are good active fliers. I fly my birds Samantha but not everyone does, they can be quite vulnerable and at a disadvantage. Some of the short-faced breeds have a problem raising babies, it's not so much that the parents have trouble feeding, its more a case that the babies have difficulty inserting a very short beak into the parents'. I guess the beak is a particular length for a reason!
You are right about the Oriental Frills, the different markings are sub-varieties.
Best wishes,
Graeme
