About a year ago I bought 3 pekin ducklings at 2 weeks old and they despised me. It became quite clear after a few months they would never like me so I rehomed them to someone with a huge ranch. Then I got a pair of pekin ducklings when they were 4-5 days old and my husband got admitted into the hospital with a bad staph infection the next day so I put a few silkies in the cage with them and we pretty much.lived at the hospital for 8 days and I saw the ducklings once a day only. They soon grew up and hated us too but not as much as the first 3 I got. But they were literally best friends with the silkies. The pekins grew, starting breeding and laying and there best friends (the silkies) just hatched the first duckling egg. We didnt want the new baby to be lonely so we bought a khaki cambell duckling to keep eachother company. The pekin baby that our chickens hatched we handled from birth (i didnt know u werent supposed to handle them so soon) well this was monday and the dang baby is so attached to us! It loves us to hold it and chases us around outside even though it was just born monday. It cries forever after we put it back in the cage and leave and when we come back it runs up to the door and pretty much says "hold me" lol but the khaki cambell we bought who was 5 days old, we've done all the same things with it and it hates us!! I think the key is handling them asap like in day 1 or 2.
