Right now my ducks are outlaying my chickens. I will clean the eggs if they are mucky (ducks have a bad habit of laying eggs in the mud to hide them). Mine have always hatched even if cleaned, its better than adding that much bacteria to the incubator. The female ducks quack and the males sound silly. Often the females will get some white feathers as they age. My 2 year old female is looking like a dalmation now. The Cayuga duck is a threatened breed and does not fly (migrate) my adults are only able to 'cruise' 3 feet high for a few yards. They are shiny black and have done well with the weather here in the mountains. Mine try to swim in the snow and are the only birds happy in the winter.... They are happy free ranging (sometimes they go far) and have a small pool in the summer as their swim source. Small tubs in the winter that freeze every night. If you have a pond or lake I am sure they would be happy and you might not ever see them again. I will ship in the flat rate boxes that the USPS has. I will pack the eggs in an egg carton and fill the box as full of packing stuff for shipping. Square (Cash) is my method for payment. Check out their site its a great app. I have had a 95% hatch rate in the summer. Doing a test right now for winter conditions, IE see how cold eggs hatch.
