That is what my husband wanted to do but I wasn’t 100% sure how my pets would react if feral intruders entered their space, and I was mostly worried the ducks might try to fly inside or that we would have a heck of a time getting them out! I am sure the Muscovy would not come in but the whistling duck would have.
My grandchildren and I went to the association pool that afternoon and some teenagers there had a whistling duck they had tamed. He sat on their shoulders, heads, and laps. He also swam in the pool, which is definitely against regulations and probably not healthy for the duck. I wondered if he lives with them but did not ask since they were not friendly — probably because we were new and they were concerned we might rat on them.
