I have heard quite a range of what each breed of duck can lay. Does anyone else keep track of this? My hens are all of different breeds and each one lays a different looking egg so I can usually tell who laid what. All my hens were born last April. I bought three runners at the ranch store, two turned out to be drakes. I bought my Campbell and Welsh Harlequin from different 4H participants at our county fair in the beginning of August, each had gotten them as ducklings from Holderreads. My Chocolate Runner was the first to start laying at the end of August. Aretha laid about eight eggs the first month, then towards the end of August she was doing an egg almost every day till the middle of November when she stopped. She lays the largest eggs and they are light green. My Khaki Campbell, Yacky, started September 23 and has laid an egg a day right up through today except for four days. She's amazing! Holderread claims to be the only Khaki Campbell breeder that keeps laying records in order to breed high laying strains. Yacky lays a light pinkish brown egg which is just a little smaller than the Aretha's, although they seem to be getting smaller maybe due to the cold temperatures? Bridgett, my Welsh Harlequin went into a molt after I brought her home in August. She didn't start laying untill October 20, laying an egg a day untill December 1, and only two since then. Bridgett's eggs are almost white and are smaller than the others. I had this wonderful stretch for two weeks where they were giving three eggs a day. Then it got cold. The temperatures around here have been usually dropping to around 20 each night for a few weeks. Anybody else?
