I have a pair of wood ducks in a large pen with a pair of call ducks. I have a next box for the wood ducks, and I check it every so often in the box for eggs. It seems that she has been in the next box because she has made a nice little "hollow" in the straw, but no eggs yet. Is it too late in the season to hope for anything this year? The male wood duck is fully into his moult, but she hasn't started yet.
