Even though my weather was fine today my power has been out twice. I have no idea why.I vote concrete in the future given how it is built. Bagged concrete is heavy as all get out but cheaper than a truck.....
Depending on how much you have to fill in it may be a decent option.
Is there concrete under where your bird is standing in the pic?
I was going to but power has been iffy here today.![]()
