Never had a duck go broody but I'm pretty sure... one of our females went missing before I went to work this morning - drake and other females acted normally so I didn't suspect a predator. Came home from work and saw her in the pool splashing around. She's quacking loudly, hissing at anything non-duck that approaches her, and runs everywhere she goes. She's wolfing food like a mad duck and her feathers are puffed up. Second question: if broody, best advice on finding her nest? I want to make sure she's safe!
