I would definitely leave them loose in pens for folks to look at. Have maybe a five pens for heifers,(seperate by age), a pen of breds, and a pen of steers. I like the auctioneer format. Then if you want to take phone bids make sure in your advertising to include sale day phones. Probaly have at least three or four sale day phones. Sounds like you got the food end of it planned pretty good, I think people really appreciate that, when they dont have to go out and get a meal before the sale. If you're going to do what sounds like a 30+ head sale, I would probaly invest in getting a sale catalog printed. I think a bag of feed and halter sounds really good, but you have to think about the cost you're going to have already invested in the sale. I'd say definitely give a halter with the animal, I think that should happen at every sale, but a bag of feed is going to be pretty expensive. And before you know it, its going to take more than one calf to pay off your sale investments. I know we give a bag of feed with every calf we'll ever sell, but we're only running ten cows. and selling in a first come first serve basis.
