This fish floated dead* in the pond so we decided to give it to the pigs. They didn’t want it. To the chickens, they didn’t want it. To the ducks, and this was their response. Yet another behaviour that we can only speculate upon. A similar behaviour occurred earlier this year, when a female duck was killed by the alpha drake, see Do Ducks Know How To Grieve.
*We have a not so large tilapia pond. Quite a number of small tilapia have appeared. I wasn’t able to catch any of the large tilapia lately because they have become smarter (and less hungry since it is chesa season and some of the fruits have fallen into the pond). As the fish population grows, the older and bigger ones die.
