So back in the spring I made a spur of the moment decision to get two khaki Campbell ducks from tractor supply. I know, not a smart decision. My family had raised chickens previously so I knew some basics. I got the ducks and have absolutely babied them everyday since so that they would be friendly. They had been friendly for all up until a few months ago when the female (Rihanna) started laying and the male (Jojo) started getting feisty. I haven't done anything to them to make them hate me. I was giving them snacks and I'm the one who feeds and waters them everyday so I thought that this was completely uncalled for. He started by just nibbling on the ground in front of my feet then started pecking at my toes. Eventually cold weather came and I started wearing boots so he still bites but now he bites the tops of my boots and where my toes should be. Also if they are out of the pen and he sees me he will run up to me and immediately try to peck at my feet and "attack" me. If I walk back to the semi fenced coop area once he sees me he starts quacking and running up to the edge of the fence and actually tries to go through the fence. If I put my hands in the fence he bites me hard enough to leave marks. And when I finally leave the area he once again tries to jump through the fence. I'm worried at this point for his safety not only because he could hurt himself with the fence but also when he gets at my feet I don't want to step on him. the female doesn't try to attack me but she is more frightened than she had been before of me. I've read things about "asserting dominance" and thats not really what I want to do. I mainly am looking for advice on how to gain their trust again and why this even happened to begin with. I apologize for grammatical errors and thank you for any useful suggestions.
