Black Swedish Drakes aggressive to owner

[birdy1]

Got them shipped from hatchery as day olds,handled daily and took great care of them,years of past experience,have had Muskoyies, White Crested, never a problem, these 2 appear to be both males, chase me every time I go outside,do not chase anyone else, even the 3 existing WC female ducks.they neck the chickens,They don't just chase, they bite me every chance they can get up behind my heels or legs. or reach my fingers.I have to carry a staff like pole when ever I go out,to keep them at bay.Will they get over this in time? they are about 8 months old now.I let them free range, but may have to pen them up so they run after me from where ever they are.Never want to give an animal away. HELP, please.
