I have 2 very healthy Welsh Harlequin ducks, same age. They both laid every day. Then one stopped after less than a year of laying. And never resumed. Its been over a year since she stopped. She's not molting (certainly not for over a year), she's healthy (I took her to vet), food was not changed, nothing at all was changed in their life. The other duck still lays every day. I cant find any answers as to why one would just stop. I love her so its fine, its just, weird.
