Hello~ Something odd is happening in my coop, There is a little door above the nest box's where there is a crack about and 2 inches wide. Yesterday, I found an odd round sort of nest in it. I put it outside in front of the door, and when I went up later it was back in in the same spot, the same nest, The on I put outside the door was gone. I took it out again, leaving it in the same place. This morning it was back in the same spot. The same nest! Has anyone had things like this happen? What is it that keeps bringing it back in? Thanks!
