for bobwhites i wouldnt pay more than 16 bucks for a pair... i get my bobs for 5.00 per adult and my californias, bluescales, and gambels at 8.00 a bird, i could see paying more for a seasoned bird if it wasnt the end of laying season but if you think about it, the buyer is now going to have to carry the birds for a full season before they lay again any ways, so in my opinion your birds would be worth less because it ages a whole year before it lays again and the buyer wouldnt get as many years of laying out of it as they would if they bought a younger pair and had its first year of breeding start next season. just my opinion of course.
