Some ducks are just weird. Mine have two dog houses with straw in them in their nighttime pen . One larger one smaller and lots of room. When they started laying I would always find the eggs in the smaller dog house. This was convenient as it is right at the front of their pen and the eggs are easy to gather from there. As more girls started to lay I would find them in the big dog house additionally or instead. This meant I had to get on my hands and knees in the poopy straw of the pen, armed with a long handled spoonish rake thing, sift through the straw to find eggs. Finally all 7 girls are laying. I always find one or two eggs in the middle of the pen, out in the open getting kicked around and covered with poop, three to five in a makeshift nest they build outside of but next to the large dog house. and the rest are in the large dog house. It does not matter how comfy I make a nest area, they lay where ever they want to and refuse to be taught or guided for my convenience.
