one tablespon per 4 pints of water , just disolve one tablespoon of molases in hot water then cool down and top up with more water to four pints ( this is usual size of a medium drinker ) , old hands used to use it as a natural wormer cant say i have tried to worm pigeons in this way but then again my birds havent got worms so it may work , mollasses is basicaly unrefined sugar in a more natural state , and sugar = glugose = energy so can give your birds a boost prior to racing and top up with pigeon tea after racing
