I ordered my first ducklings! I am getting Ancona's and Rouens and I'm curious, if they breed will their offspring be infertile? I've tried looking and all I can come up with are threads on Muscovies. I know mixing a Muscovy with another breed leads to infertility and no eggs but is that true for other breeds? I know its a stupid question but I just want to make sure. I will hatch eggs out and keep/sell the pure Ancona's since I know they're endangered but will use the mix breed for meat and maybe try out a couple as layers and see if egg production is changed, better or worse. Plus, I'm kind of excited to see what that mix would look like! Thank you!
