I live in a neighborhood that has a couple of 10 plus acre lakes. The "front" lake has always had Muscovey ducks, the "back" lake that I live on never had ducks. Last summer I raised 3 Peking ducks and 6 Rouen ducks from chicks. I would love the Rouen population to grow. Walking around the lake this week, I saw 3 random eggs in about 6" off water near the bank. I built some nesting boxes, but so far they want nothing to do with them. Tell me what I need to know................ Are these random eggs potentially fertile? Should I put them in an incubator? Is there something I should do to help with the nesting / reproduction process.......or should I just stay out of the way? I want more Rouens, would be a fun exercise for me and the kids to help the "process" along with the existing ducks. All help and advice is appreciated.
