I had 3 mallards I bought as ducklings that were 3 days old and they followed me everywhere, and I still have one of them and she comes when I call her name most of the time. Other batches of ducks, mallard and otherwise, were different, but I don't think they ever hate you. They are naturally skittish, some breeds are more likely to eat out of your hand, but in general, they all go through stages too. The batch of ducklings I raised this year did that. They would only go in the pen when herded into it, but now they come when called and will eat out of my hand. I chalked it up to them being so many of them at once. I raised two ducklings later in the spring, and they were pretty tame with me until I put them out with the other ducks, then they got more independent of me, but they came back to me. Give it time, spend more time with the ducks, spoil them, make it so they trust you. They will.
