I have two ducks who are around 5 and 6 weeks old and I didn't start trying to diaper them until they were 4/5 weeks. Whenever I get the diaper on them, they FLIP out and just start running around trying to shake it off until they get it off. I'm worried that they are going to hurt themselves getting it off, and it makes them run away from me if I have their diaper. Did I wait too long to start trying to diaper them? Are they ever going to NOT hate it?
