hi! I breed and show Belgian d’Uccles. If you are participating in showmanship (an activiry that is held at the poultry shows, you will basically stand there with your chosen bird demonstrate the different body parts, how well handled your bird is, and the info you know about it, anyway that’s for people under 18, consult YouTube if that is something you’d be doing)
showmanship requires a dress code, typically close toed shoes, dark pants, a white shirt and your hair back. Unless you are doing that you don’t need to worry about dress code.
To know what your bird is supposed to look like you can reference the
APA (American Poultry Association) standard of perfection, and the
ABA (American Bantam Association) has a version as well. It will also tell you what weight your bird is supposed to be at. But you really don’t need to worry about weight, as long as they aren’t visibly under or over their desired weight. I’ve also heard of ties between birds being settled through weighing them…
Your bird should be bathed, toenails trimmed and tidy, and beak as well (no overbite or anything funky like that) they also look nice with a bit of baby oil on their comb and wattles. That entire procedure as well as how to actually bathe a chicken is super easy to find on YouTube.
Best of luck with your show it’s a lot of fun, you get to meet all sorts of interesting people as well as their birds lol
