It must be mating season, i often see two or more ducks go after singular females... Sometimes, in the water the males can even drown the female when mating with it...
Just like elephants i suppose - Hormonal rush bought on by the seasons.
Well..... looks like you did good, may as well eat em.
Thing is I have way more females so I don’t get the excitement. They have attempted to down a few females. They needed to die.
Yes we did eat them and they were good. 😊
