I'm near Dunnellon Fl. NOTHING is too heavy to move. You should see our tractor houses. They are on skids and they are pulled by a 4x4 just a few feet over so the grass can rest.
Looks like a good set up for 5 birds.
Good job and good luck.
Relocate it periodically. Looks light enough.
Perhaps fasten some drop down wheels as well. Each time it is moved, the earth has been fertilized and grass will grow back quickly this time of year.
What part of the peninsula to you live in?
