This morning I went out and threw some cat food around as treats for the chickens and poured some feed in a dish for the remaining 2 Muscovy ducks that have managed to survive loose around my house. I then went to open the chicken coop to let the chickens out. I watched in disbelief as one of the Muscovy calmly waddled up the hill and into the coop. I thought she must have discovered their feeder. I didn't think much more about it other than it was unusual. After she didn't come out for a while I started to get curious. I opened one of the coop doors to see what she was up to, only to find no duck at the feeder. I then went and opened the nest box on the far side. Low and behold there was a big duck rear winking at me as if it where about to drop an egg. I closed the nesting box door real quick, and she went over to the next nest box. So I got to thinking about it and we have been getting more eggs in the coop than normal and some of them almost do not fit in the cartons they are so big. This sneaky duck is going into the coop, leaving her eggs, then going back down to the pond like nothing ever happened. This is a good thing, but I was expecting her to lay there out int he woods or something. How unusual is this?
