Help! I purchased some ducklings last spring (runners and campbells). Ive had them on duck grow and whole corn on the advise from the folks at the feed store. I also give them spinach and other finely chopped veggies at least twice a week. They are free run and seem very happy except that they have stopped laying! I started getting eggs in november and things were going great until the cold really started to set in after Christmas......since then, nothing! They are kept in a nice sized coop but I let them out for at least four hours a day in the winter unless its REALLY bad out. In the summer they were out all day. Clean, well fed, watered.......what am I doing wrong?
