I just read a short recommendation on another forum for the Muscovy duck. It claimed they would kill and eat mice and rats. True? While rodents have never made their way into our chicken coop (which rivals Fort Knox), our outdoor rabbit barn has attracted mice and a small variety of rat that has recently popped up in our valley. I went out to check on a littler of kits one freezing cold night and found a small, kit-sized rat curled up in the nest box with them! They have also taken up residence in the storage shed. (Food is protected, but I guess the shelter is irresistible.) The rats only occasionally are tricked into setting of snappy traps, and since we free-range our chickens, we won't put out poison. We have talked about getting a couple of cats, but not all cats are mousers. Would a few Muscovies take care of a small rodent population? Will they play nicely sharing a 2-acre spread with a dozen or two chickens? How aggressive are the males? I don't want to worry about scaring the UPS lady! She was not too happy with the Tom Turkeys we had one year. One of them had a crush on her. =) We have a 10 x 10 magnum kennel (tarped roof and sides during rainy weather) would this do as an enclosure for nights and rare days away? What kind of roosts are appropriate for this breed? Thanks for any information you can share.
