A few days ago a hawk got one of my ducks. Since then I have only gotten a couple of eggs. Are they not laying because of fear from the hawk? They are not being allowed to free range now but they are accustomed to being in their pen. Or do ducks go through a spring molt where they do not lay? If they do how long will it last? I was planning on hatching out some chicks soon. What can I do to encourage laying?
