Hi! I breed Muscovy ducks - a personal favourite. This year however, I have had several requests for different kinds of ducklings. I would like to hatch some Welsh Harlequins, but there seems to be demand for Khaki Campbells near me! Since these breeds both have slightly different hatching times, I don't want to place all of the hatching eggs I would buy under my female at the same time. I realise I could add more eggs a few days later - not a problem for her as Muscovy ducks have a 'the more the merrier' attitude. BUT my question is... If she hatched say 12 khaki campbell eggs, could I buy day old Welsh Harlequins and add them to her clutch once her eggs had hatched? Or would she know they were different and abandon them? Bear in mind that she is a very broody duck! Thank you!
