VolunteerChin - I personally LOVE eartags. I have enough animals that it makes my life a lot easier. I often tag when I wean. If you don't have tags, don't know how to tag, or don't like the tagging yourself part of it, usually each branch or a rancher will have some spare or blank tags and will tag the chin for you. Just make sure you let the branch know ahead of time so they can be sure to have them there. The tags help verify the animals if say some got out. Say two animals got out over night in the morning you can verify the animals owner by the tags.
I also understand your concern with the age groups. But in the end they all go for the same award, grand show. To me if an animal is going to be shown it should be able to compete against all of the other animals there. There are have been 6 month olds that have easily beaten out older animals, and even taken top awards. I know I had a pink white take Champion White at a show at 5 months old once, because that day he was the best animal there. I showed him again later and he received a 1st.
I am also a fan of the 10 class show because the class is not full of one person's animals. Say something like Ralph Shoots was to show, he could easily have most of the animals in an entire class, in a 10 class show every animal is judged against each other and one class can't have a bunch of one ranchers animals in it. I personally feel that this offers a wider range of chins to compare per class offering a more consistent selection for the judges to work with. For example I could take a whole chunk of animals that are very light standards, and easily win a light phase class, but say Ralph Shoots can come in and over take the dark classes. My light phase animals won't even come close to what Ralph brought, but yet they received class champion the same as Ralph's. I hope that made sense to someone other than me.
For those who don't know a ten class show is based on simple numbers. When each breeder comes in they get numbers for each of their cages. If the first person brings 10, they are 1 - 10, if the next person brings 7, they are 11 - 17, and so on and so forth.
Say for ease there are 100 animals present, they are then split into groups by the last digit of their cage number. So cage number 1, 11, 21, 31, etc. will show against each other regardless of age, sex, color phase, etc. In this instance the first person to sign in would have one chin in each class, so they are not competing against themselves for a class award.
ECBC does not run the mutation section this way. Mutations are divided up into simple colors. White with dark ears, white with pink ears ( pink white), beige, violet, sapphire, ebony, tan, etc. But the whites all show against each other regardless of color phase or markings, etc.
I hope that I got that all clear enough not to confuse anyone.
