I lost my runner babies my mini duck brooded last month. If I put eggs under her will she go broody again? Or is it a seasonal thing? She isn't laying and had finished laying right about the time I put the runner eggs under her.But she was a faithful little thing. Also, my runners have been free ranging in daytime in the fenced area and are interbreeding--if I wanted "pure" eggs of the right kind to hatch how long will I have to separate the two breeds of ducks so they aren't bred by the wrong drake?
