This may sound dumb but does anyone else's ducks never go into the cozier box. I made mine a box with shavings in the bottom of it that is pretty similar to a nesting box just a bit bigger. I dont think I have ever seen them willingly go in. They are about 4 weeks old and have been outside for almost 2 with it recently dipping into the mid 30's at night. Every time I look outside and check on them they are outside huddled. Is that just what they like or are mine just rebels? Also while i've got you any advice on duck nesting boxes?
