I will also give an honest opinion as well. Showing for fun would be just showing for your own fun, not your birds. Showing puts the birds under undue stress and exposes them to potential disease, and parasites from other birds. It's not unusual for me to leave my absolute best birds or favorite birds at home for just the reasons mentioned above. I don't want to risk loosing them or having them pick something up at a show.
I show and do quite well, but I show with a purpose and that is to win. I also do it to help promote the breeds that I show and to help encourage other people to show competitively.
I've clerked a quite a few shows and when judges see birds of extreme poor quality, or production quality they usually shake their heads and mention something along the lines of 'shouldn't be in a show'. A lot of times they just give them a quick cursory look and then pass on to the real competitive birds. I will add this though....when people show the poor quality birds, they are usually poorly conditioned, not washed and it's not unusual for them to have mites etc. The judge does not want to handle them as he has to handle other birds next and does not wish to pass anything between birds.
Ok, that's the negative....onto the positive aspects. If you prepare your birds, they are healthy, you treat them for parasites before and after the show then you will be seen in a much better light than if you did not prepare them properly. Showmanship is an excellent way to participate in the competitive level of showing without needing show quality birds....but conditioning counts big time, as well as having a good understanding of the breed you are showing. I would much much rather see a well conditioned cross breed being shown than the highest quality show bird that looks like it just jumped in a mud puddle and rolled around while having it's tail plucked.
One last point. If you win or loose conduct yourself with the utmost dignity. No one likes a gossip, someone who trashes others behind their back, or is either a poor looser or a poor winner.
All the best in your adventures!
