RATS! My 6 chickens and 5 ducks share a 30' x 50' covered run with a large coop at one end and a small pond on the other. We have a barn cat, but he is not allowed in the run (he once got in and killed a full grown hen). He has driven the rats out of the barn...and into the chicken coop. The rats have driven the chickens and ducks out of the nesting box and most of them have stopped laying or lay in the run. Although I cover the food each night, there is enough scratched and spilled out to keep the rats fat and happy. In an attempt to control the rats I have set electronic traps which have proved to be pretty much useless, so I resorted to setting 10 snap traps in the coop each night. I have to close everyone out of the coop so they will not get caught in the traps. That is how I got the male, but the female is just too clever, and now she has had babies. (I have a night vision ip camera in the coop so I can actually watch the little buggers at night see below.) Also, any bait (peanut butter, horse feed, peaches, cat food, parsley, limburger cheese etc) I use in the traps is usually overrun by ants by morning so now I have an ant problem to deal with as well. This is just not working So my next thought was to get a treadle feeder and see if that works. They advertise them as limiting spilled feed. No food...no rats...maybe. But I have to consider the pekin ducks as well. So my question is does anyone have any experience with the Feed-O-Matic feeder https://youtu.be/MxSAFVOInqs (or any treadle feeder) and ducks? I can find no information on using a treadle feeder with ducks. More to the point, if anyone has a better way to eliminate rats, PLEASE let me know. I am resisting the urge to buy a night vision scope for my pellet gun and sitting in the coop all night. I think that might be too extreme. Night vision screenshot of Rat laughing at my traps.
