First of all, we are newbs to ducks, or anything besides a dog, so we are learning as we go along. We have 2 ducks and a drake inside the converted dog house, and on one side I have the door removed so they can come and go into their enclosed shelter. But, to reduce wind I wanted to hang a piece of plastic (think white trash bag) over the opening and put slits from top to bottom. Do you think they will still go thru it to get their food, or will they be too afraid to push thru? Yeah I know I can build it and see what happens, but I hate to waste the time right now...I beginning to build a laying box to place inside the dog house/coop. Thanks for any input.
