I have 4 ducklings that hatched on Thanksgiving. I was there when they hatched and even had to help 1 of them out of it's shell. I let them dry off in the incubator and then spent a lot of time holding them and they would follow me around and eat out of my hand. I moved them to the brooder and now when I go in by them they all freak out and run away from me. They are terrified of me and just run away. I'm confused because I thought ducks imprinted and I was the only one with them from the time they hatched. Any advice on why they changed so fast and why they didn't seem to imprint on me?
