I'm having trouble with one of my girls. She started going broody on a nest of rocks (no clue where she found rocks in the barn or HOW she got them in the nest). She stopped laying so I took her rocks away. But then she never left her nest so I took the nest away. (-29 is way too cold for her too be out in the barn with no heat in my opinion). Its been a week since I took away her nest and She's still not laying. Neither has she built another nest. (At least then I could slip my other ducks eggs in there). Anyone one have any tips?
