Hi, so i'm getting a little nervous its starting to get cold and my two ducks male and female, wont go in there nest i made. what it is, is a barrel on its side i cut out holes in the front and back camouflaged it well, filled it with straw around the whole in side, and its up on a pole maybe 8 feet off the ground next to our pond. i got the pair as babies this year in April, when a man who had them in a tote didn't want them,i was totally unprepared and have never had ducks but i felt my home with a pond all to themselves was a way better future, i can feed them and they come up to me but i cant hold them or anything, i'm just getting worried about them getting cold the temp at night is now 35 degrees, do mallards live in the snowy weathered places? idk someone shed some light on my ducky's who i'v grown to love very much. thank you for the help!!
