Hi, I want to make a small list of when certain breeds will be laying and for how long they will be available. I have some ducks, but am not familiar with some breeds. Please share your experience with how long Mallards are available. What about Mandarins and wood ducks? Some other breeds like Rouen. How long will they lay? I would like to link this information to the breeders list, so people can see when they can purchase certain breeds. Thanks.
