Greetings! My fiancee and I have 3 female and 1 male young adult ducks. Every night we usher them into an extra-extra large dog kennel and cover them. The kennel is right underneath our bedroom window so we can hear if anything is going on. They sleep through the night and wake us at 7 AM like clock-work. Each morning one of us goes out, uncovers them, and opens the door. We always feed them in the morning and they used to come out and watch us toss the food in the yard then run like crazy to it. The problem is, as of late, they WILL NOT come out of the kennel. Today they spent 2 hours still in there, even after having shown them that the door was open. I have tried tapping on the back of the kennel, lifting up the back of the kennel very slightly, knocking on the back, and everything in between. I have tried putting some of their pellets right in front of the open door to coax them out- to no avail. I actually had to put a little of their food inside the kennel to keep them from "screaming" at us and upsetting the neighbors (we live in a suburban neighborhood). Is there anyone that can help us figure out what is going on with our babies? Thank you all so very much!!! The duck setup: The kennel is the plastic kind with the ventilation holes on the upper halves and a wire door. One long side is up against our house (not flush so there is air-flow), the back has no ventilation holes, which leaves the other long side and the door uncovered. We cover the door with a tarp so they can sleep (our ridiculous neighbor leaves their two porch lights on all night). On rainy nights they are completely covered. Also, they do have a kiddie pool that we clean out about twice a week that they swim in and drink from.
