We have three muscovys, three pekin-types, and two geese. Previously the pekin ducks and the geese were tight and the muscovys were a little group of their own. One of our muscovys just had 10 ducklings and after six or so weeks we gave them away. We noticed soon after that the mama muscovy was sitting on her own all of the time and I wondered if she was depressed about losing her babies (do ducks get depressed?) After more observation I have seen the other two muscovys (one male, one female) chasing the mama muscovy, hissing at her, and trying to attack her. They won't let her hang out with them anymore. Can anyone give me some insight into what is going on in my garden? I'm perplexed. This is like some weird high school drama.
