Dr. Luke-
I have a couple ponds in southern Iowa and have put up 2 wood wood duck houses and 2 plastic type house. Each winter I place new wood chips. I have been at this for 5-6 years but have never had wood ducks stay. I occasionally will see them on pond but never any chicks.
Any advice on getting wood duck to stay in houses. What you use to line bottom of house.
Tom
