Hi! We are very new duck owners and love them! They are about 4 months old and we have lots of questions. I don't even know what sex they are yet. My primary concern is we live in Oklahoma and winter can get very cold with ice storms & snow. How do they do outside? They have a small 2 level coup (picture below) but they won't go up and down the ramp (scared of it?), so they won't get upstairs to the hay filled enclosed shelter. Its hot now so they only go inside it to eat right now. Also, we don't have a pond but use a kiddie pool for their wading/bathing water. Do they need this in the winter too? I'm sure it will freeze. Any help/guidance is appreciated. We sure love them and want to keep them around, we're just very new to this. Thanks in advance!
