I have not shown birds since I was a teen but have attended shows just to help exhibitors and I will offer to help someone out if they have breeds that I am interested in learning about especially.I would agree with Walt about getting to shows, there have been a few shows where we have taken birds, and the condition is not where I would like it but representing the breed to me is important especially the large fowl and in our part of the world there are not many shown. But the greatest part of a chicken show is the talking with other exhibitors. There is no other exhibition group that I have been around where information is so freely shared.
We especially enjoy showing our large fowl and had some success on some days, all our birds are naturally bred tend to be vigorous and lay enough for us to be able to keep few for breeders, eat a few and sell a few.
AGAIN Get to a show or two even if you are not showing, it is amazing how friendly the poultry groups are in general and even if you don't talk to a Cornish breeder there is lots to learn.
