Hi I have black and blue Cayuga eggs for sale. The Cayuga duck is a medium sized duck with the black ducks having a beetle green sheen. The blue Cayuga was developed by Dave Holdereed. They have the Cayuga body type with the unique blue color. I have my blacks and blues running together to get the best blue color. You may get black, blue or silver ducklings the color genetics is the same as blue color in chickens. I am fortunate to acquire these beauties from Sandhill Preservation and Holdereeds am trying to further the breed. All my ducks run free range and have a pool to swim in. It is spring and the girls are really laying. Fertility has been checked and is great. I gather eggs every day and will ship only the freshest eggs. I can sell these in lots of 6 plus any extras at the time of shipment. The price is $1 per egg or $6 for six eggs. I have no control once they are shipped so I can not guarantee hatch rates. I wrap each egg in bubble wrap and carefully pack each box to minimize breakage. Shipping is $10.00 flat because these are heavy eggs. Any questions please ask.
