4-H is a very good organization to get involved in. Of course a lot depends on your group leader, but most of these people are very good.
Clint, my son and daughter always took lambs and they were really good for them. Last year my son switched to hogs. The lambs just got very expensive and it was easier to find hogs. At our fair you are allowed to sell one large animal and one small. Sheep, hogs, feeders and fats are all considered large animals. Goats, rabbits, chicken and turkey small. My wife and son missed the lambs so we got goats so we could still sell them. No use getting really expensive lambs we couldn't sell. They like the lambs better, I kinda like the goats but we haven't had much trouble with them yet.
DC our kids raise the animals and show them. They lead them around the ring. There are contests for showmanship and the animals themselves. They keep a record book of their expense they turn in at fair time. Local businesses buy the animals usually at a higher than market price and many offer them back to the kids at market price. It's pretty though on these kids selling their animals, especially the first time. They get a lot of time into them and get pretty attached. I'm pretty sure Charlie will be bawling in the sale ring. Maybe grandpa will have to buy them. It is good they learn how to raise them and where their food comes from.
