Ping and Paddle, my two Pekin ducks, are 20 months old. They both started laying at about 5 months of age. They laid an egg a day each pretty regular except during the really cold months and when in molt. In June they went into molt, came out of it just fine, and have not laid an egg since. Either one of them! Their food has not changed. They seem very content and happy and do not show any signs of disease or stress. I miss getting their eggs!! Any ideas of why they quit? Any help would be appreciated.
