I'm trying the easiest idea first, since I'm a bit construction-challenged, a lifting rack with 2x2's.
Asked Hazel and Peanut for help with the math in calculating where to put the cross-pieces, and I added I was asking them because "chicken math" is so famous. They stopped in their tracks and gave me this look:
They said they really prefer inspection, adding that it appears to be roosting bars I'm making.
They proceeded to step on and hop over with muddy feet, back and forth, and also squeeze under them. I guess it passed some sort of inspection
. But later Butters (structural engineer, based on her inspection of the perch concrete blocks last year as @featherhead007 noted) said it's too early to judge the structural integrity, and she's right.
I discovered the two greenhouse frames have different section widths, so I marked the wood for the narrowest one. Hopefully.
