Hi Spencer!
First of all, let me just say...."Yay" that you're going to show! I think that is wonderful.
As a newbie to poultry shows (my first one was just last month), I can only share my thoughts, but beware they are mostly bereft of the vast experience many others have here.
Yes..go. Here is what I do - take this with a grain of salt
I mentally reserve at least one male and at least two females from each variety to stay home and out of any risk. Those birds may not be your very best, but should be acceptable breeding quality so that, if some unforeseen disaster happened and you lost the birds you were showing, you would still have a back up plan in place.
I'm going to take my very best male of each variety because I'm going to win, not just to pay entry fees.
When I only had one cock bird in blacks - he stayed home, but now that I have several, I'm taking the best one out there...or at least the one I think is best. So, that's my first choices - the best of males of each variety.
I'm going to select a couple of females from each variety - I'd like to take the very best and the second best, but I realize I may have to leave one of those behind....just in case (see above)
My selection process will also include the decision of who is, or will be at show time, closer to being ready to show. If my best male is 4 months old, then I'm going to leave him for the next show and take the next best male that is closer to being ready to go before the judges.
Then, I'm going to take every precaution that I know to take to make sure the selected birds have good strong immune systems before heading out. There are many theories on how to do that, but a couple of highlights - I'm going to make sure those birds are internal and external parasite-free. Parasites can bring a bird down and weaken it's immune system. I'm going to make sure the selected birds are of good weight, healthy appetites, and otherwise healthy - no leaky noses, coughing, or any evidence of disease or illness. Not only do I want to protect my birds, but I also don't want to take a sick bird that may infect other birds while at the show.
Once I've done all that - it's showtime!
And you know what the best thing about showtime? Getting to meet new friends and spend time with old ones, chat about your birds, and get to visit. I've shown in dog shows and horse shows all over this country, but I've met some of the nicest folks at a poultry show.
Those are just my thoughts...hope it helps. Have fun and be sure to let us know how it goes.
