I've got an old Remington pocket knife with a gut hook. I drop the guts (quail) ASAP, no later than at hunt's end, because of its digestive juices permeating the meat through shot channels. Never have a tainted taste with doves, however. Quail eat a lot of hard seed which requires a turn or two in the gizzard then strong digestive juices. I age woodcock with guts in. Never had a problem with taste with dove or woodcock when leaving guts in for several days refrigerated before cleaning. Gil
