I don't hang it. If it's been hit by a car it won't be a clean kill so I like to get it stripped and jointed ASAP. Baby rabbits are lovely just dipped in flour and panfried in butter - older ones are tough and need casseroling. For a pigeon, don't bother plucking just skin the breast and cut that off, throw the rest away its more work than the result is worth. Pheasant is difficult to tell the age, if its legs look tough, yellow and scaly then its probably older and tougher. The trick with pheasant is to eat it either rare or cooked for hours, anywhere in between its like leather.
