We have 17 pullets in a large coop and run in our backyard. Recently the hubby and I have been tossing around the idea of getting a few ducks. I need all the info possible for care, housing, and behavior for these. Which are GREAT layers but also very friendly as we have 4 human babies. What do they need in a coop and run, how do I set up the coop, do they use nesting boxes, ect. Please help out. Also, are they good cold weather animals? We are in oregon where we deal with nasty rain, wind, and a few nasty cold nights.
