I was wondering about fertility. Did you notice it drop after 5 years? What was your indicator? Meat is the goal for ours. And being from mixed enterprise farming family, completely understand the culling of something not producing anymore, as sad as it is you can only feed so many mouthsAs for me, I don't think I've ever had Muscovies older than 4 or 5 years, but that's not because they die on their own. I cull my older Muscovies and replace them so that they have higher fertility rates and hatch more ducklings, because I raise my Muscovies for meat.
