I started raising ducks starting in spring my 18 ducks grew up splended!!! I have 9 females 9 males they don't attack and each othe. We have been pretty good about about picking up eggs. One day I realized while feeding the ducks that one was missing I end up finding it in the corner of our shed (where they sleep at night) laying on eggs. So I was wandering are they going to be alright? I been monitoring the eggs it looks like they are about 12 days in so I don't know what to do? Plus I live in Nebraska but it has been a mild winter so far. Any tips are welcome!!! We do keep the shed heated and closed at night.
