Oh, you are using treated wood. I couldn't tell from the photos. Some of it is better than others, I have found. I remember getting some "treated" wood from HD and it was basically just coated on the outside. A piece of it laying around in my yard was eaten by termites. TimberSIL is the best (wood infused with liquid glass). The termites won't touch it, and it is rot and fire resistant. However it is darn expensive and the closest dealer to me is CA.Termites won't eat treated wood. Put a little bleach in the water every once in awhile will keep the algae out.
I like your pens. I need to either build more for the males or cut back drastically
