Yikes! I need help with judging goats

The superintendent of our local agricultural fair phoned me last night to ask if I would judge a small dairy goat youth class in a few days. Because we had dairy goats 25 years ago when our daughters were small (and, I suspect, because she wasn't able to find another judge), she thought I would be a good choice. I asked her to look for someone else as I really don't feel qualified, but I'm thinking she won't look very far. Anyway, most judges won't travel far to judge just a few animals. If I do end up pressed into service, I'd like to be as fair to the kids (human & goat) as possible. Does anyone know of good reference material I can use to study (more like cram) for this event? Thanks!

 

Thanks for the responses. I will be judging showmanship which isn't so difficult as I've watched countless shows involving our kids and many, many nieces and nephews show in youth showmanship classes. My difficulty will be in the conformation classes--the difference between a good goat and a bad one physically speaking. That is where I'm uncomfortable. Any ideas would certainly be appreciated. Well, I can always hope that someone more qualified will be located. It shouldn't be hard--the more qualified part, I mean.
