And I do appreciate the advice.This is true but a bird with a frostbite comb is also 'not showable.' Of course, you could enter such a bird in a show, but he wouldn't place well. Besides, exhibitions are for showing off the best we have. This is something many don't seem to understand about Shows. Condition means a whole lot when it comes to judging a bird.
I see folks who have never even been to a poultry show pick up some dirty old chicken, stuff it in a carrier and enter it in a show (and then wonder why their pet chicken didn't win). This is a ridiculous type of attitude.
I was suggesting dubbing because obviously this particular bird is not a show bird but a breeder. Frost-bit combs can/do affect breeding. Thus, my advice to dub.
The first show I went to as an adult, I saw the dirty old chickens to which you refer. I remember thinking that all my birds looked better than most of those being shown.
A couple years later the judge from that show bought some of my chickens. After examining each bird as he pulled them out of the cage, he said "you sure have some clean birds".
It made me feel pretty good.
