I have seen so many people back away from buying a female, simply because the seller wants to retain a flush even at the buyers convenience, that I have come to the conclusion that it probably does nothing to help the sale of the animals. In regards, to keeping a flush in all the heifers in a sale, I think this is a sign of a seller getting too greedy. If the seller wants me to pay a good price for his females, why can't they come back to me and offer to purchase a flush if they want one?
Two years ago, I was working as a sale rep at a sale and I was able to get a very good bid on a couple females in the sale. Shortly before the sale started, I received a phone call from this person and they told me they were withdrawing their bids, because they had not seen at the seller was retaining the right to flush females in the sale. I could not change this persons mind, and as a result, I lost the bids. I am quite sure I could have purchased both females because they both sold for considerably less than the bids I had got originally. Since then I have oftentimes wondered how many times this actually happens. I have seen it happen more than once. I used to retain the right to flush certain females I sold, but do not do it now. I feel if the female is worthy of being flushed, I can buy a flush back from the owner. If that is not possible I can always buy some of her progeny.
