I planning on putting out a few houses this year. I had three over and my Uncle's place and got woodies and hoodies to nest there. It was cool but he sold the property but now I have my own with 3 ponds on it. Stopping by Menards to get some 1x10's tonight. That's crazy seeing that coon climb up the galvanized pipe. That's what I as planning on using but in deeper water.
I'm putting one on each of our ponds in the next week or so, with sheet metal guards on the posts.
Also putting up four on a buddies property on river.
The ones I'm putting up I got from ODNR three fiberglass and three wood.
I have 2 box's on my small 1/4 acre pond. I don't know if it matters or not but I tried to keep the houses out of sight from each other. I had a hen nest in one of the box's last year
Interesting on the nest dumping. I read a article and it said NOT to put wood duck houses close together because nest dumping will happen. It said to put the houses up where one house isn't in view of the other. The article I read said nest dumping was not a good thing.
I read a study I found on the internet that was done in the Dakotas on the placement and preference of the nest boxes before I put mine up.
It said that facing them east was better if they were in open due to the heat of afternoon sun and that hens preferred wood over fiberglass or plastic. Don't know if any of that is really true or not but I tried to set mine up to be as duck friendly as I could.
We have a good size local waterfowl refuge here and they have hundreds of boxes out around the lake made of all kinds of things and over the years I think I've seen hens at every type.
IMO the biggest factor for success in my area is some type of predator guards.
We put up my buddies nest boxes along the river yesterday, three fiberglass and one wood. They are from right along the bank to twenty yards back from the water, all four of them are from 12'-16' high.
The area can flood pretty bad so that is why we put them so high, now hopefully the wood ducks will take a good look at them a few weeks from now.
