On the coop card you have " C ", "H", "K", and "P"
"Cock", "Hen", "Cockerel", and "Pullet." It lets the judge know right off what age group your bird belongs in.
I don't think anybody is haughty or trying to humiliate anyone or make them feel like they're an idiot. In the world of show poultry, that is the language used... just like in the dog world, the ***** word is something I never ever use. Not because I'm not in the dog world but just because I don't like the sound of it but if I was to enter the dog world, I imagine that if I was to call my female dog a female dog, I'd get some pretty strange looks. So, if you want to fit into the show poultry world, you call your rooster a cock bird. I've never experienced any attitudes from those who have been breeding/showing their birds longer than I have. In fact, when I first started, I probably used the term "rooster" I don't really remember. I think if I had received any response to it, I would have remembered that.
So, you don't have to live under your rock, just realize that no one is trying to isolate you for the words you use.
