My Wood Ducks showed up around here about March 6th.... maybe the 8th. Seeing as I just retired from my full time job I got all my nesting boxes cleaned out, changed wood shavings if needed and made a few more. I have 33 boxes out now. Got a couple more I may put out if I don't sell them first. It's a fun project I have been doing since my kids and I made a couple boxes way way back in the 1980s during a winter blizzard in our basement. I just replaced 1 of those wooden boxes this year. It was patched upa bunch. Now I make em from PVC and they work great. I get up every morn and walk over to the creek (about 30 yds from my cabin) and there is always 3....4 ...5 or more pairs of woodies always swimming on the water. Haven't looked in any boxes but I am pretty sure the hens are laying. And I ran and cleaned all my Blue Bird nests out. Made a few more of them also. I have over 70 of them scattered over a large area. Usually have about 2/3rds of them with BB each year. A couple projects that get me outdoors in early spring.
