My DS, Hot Wing Stables, shows modern games and OEGB for 4-H. They have the best personalities. They love to talk to us, they jump on the ledge of their pen, so we will pick them up and tell them how beautiful they are. They are my favorite of all of our birds.
I think you just need to be careful when you dub the roosters, as to who might be around to see. I was told that if you have proof that you are in 4-H, a member of the APA or ABA, and that dubbing is a requirement for showing the birds, you should not have any problems. At least that is what we are counting on.
As for summer, my flock did pretty well last year. They are in an enclosed stable which is covered, and has a lot of ventilation. We would put a mister in the pen and the chickens would walk through the mist, or take their dirt bath in the wet sand. We just made sure there was a lot of water.
Have fun with the site!!
