Chickens its very unlikely to taste of anything fishy or nasty. My friends killed, butchered and ate an 18 month old boar who had fathered many piglets, he was delicious. The chops were a tad large on the plate. Never had boar taint, and if you do just turn him into sausages, bacon and gammons. There is a lot of urban myth about boar taint, its not getting the pigs too fat that is the problem.
Bon appetite. HM
