find a nice 4h group and they will start you off with a project/activity book. though its not just about showing the animal, there's skillithons, you have to make certain posters, you have to complete required activities such as community service, and go to seperate judging where its just you and the judge, no animals invalved. its quiet hard, since, depending on your 4h group you may have to go to other shows, not just county fair shows, like mine, but thats not always true. But its very rewarding and fun, and you aslo learn responsibility and life long lessons. they trouble you might have is your son is only seven, and if his birthday was after jan. 1, 2005 hes still considerd 6. To join 4h i think you have to be 8 and in 3rd grade, though things may have changed since i joined. ( i couldnt join because i was 8 but not in 3rd grade so i had to waith another year,) though it may be different where you live. contact your local county extension office. But if hes too youg he could be a cloverbud, so he wouldnt get judged in the same way as 4hers would. But i would go to the county fair, talk to people, watch the chicken judging( you get judged in an arena, exciting) and maybe talk to some judges befor geting started so things wont be so confusing, because it can get quiet confusing at times. Good Luck!!! (sorry its so long)
