Don, at the 2017 ABC National Show in Hutchinson MN, for the on site items on auction we put an open bid form for each item. It was surprising how many bidders kept coming back and checking on their bid. Many were outbid so they re entered a new bid. I think it was harder on me at the ABC table watching the bidding as there was this semi-elderly lady that really wanted one of the items. She kept re bidding, but was edged out at the last minute. When she came back, I had to tell her that she did not win, I felt so sorry for her! On the other hand a young boy wanted to bid on the Bantam 4 hole show box. He finally convinced his mom to bid, and bid she did. After many bids, much to Jan Geis dismay, he prevailed and Jan had to settle for the Bantam 3 hole show box.
On the Spring Egg Show contest, I know personally I value every egg to the incubators. I always have requests to buy eggs, but my eggs all go to chick orders and my grow out stock.
