Just got some Black calls / East Indie / magpie marking call ducks. Said to be 3 months old and look ok. The flock the ducklings were living next to may of had worms, noted by my son in some fresh chicken poo. Due to age, wormer of choice? How about DE in the feed? How long should the quarentine be from my resident flock? Not neccessarily but in addition to the worm, they could have anythingb even thought they look ok.
