I had a few ducks years ago, khaki Campbell's, and Muscovy's. I liked how my khakis really went out and scrounged during the day, they were never still, always eating bugs and slugs etc..however I found the khakis very delicate. A couple of times the young kids dropped the khakis over the fence after they got out, and they fell-- I didn't think it was too hard- kerplunk, and immediately fell over dead!! It got where they were gently placed over the fence, as several died, and one went into spasms for a minute before getting up and walking away.. we were in shock. The only thing we could figure is the bump on the chest effected the heart.. The muscovys on the other hand were the laziest bunch of free loaders I have ever seen, they wouldn't scrounge for anything, I never saw them ever look for bugs, and they just waited around to be fed grain, I even tried cutting their grain way way back, but they would not look for bugs. On the other hand they were tough, they would fly over the fence and land with a pile driving crash and get up and walk away.. Every one I have ever spoke to who has muscovys tells me they are the best bug getter of all times.. I got my muscovys from several different places, but it didn't matter, they just stood around all day waiting to be fed, while a few feet away the khakis were snapping bugs out of the air.. Did I have weird muscovys?? I have thought about getting back into ducks, and there are plenty of Muscovys around, but hesitate because the ones I had were very lazy.. I want something that will clean the bugs out of the garden, and supply meat, but they were ALL so very lazy, and most were "duds".. where my muscovys normal? any thoughts?? thanks..
