Wishing you luck with the cinder block beds! I've tried them for a few years but won't use them again. They require more water compared to wooden raised beds, and since my soil is clay-heavy, the blocks settled with proper prep. Growing small, drought-tolerant plants in the block holes was interesting, but that's about it. I'm in zone 7.
I thought I saw a few ISA brown hens which lay a lot of brown eggs. Thats a good haul. Best part of the day is eating eggs for breakfast and then collecting more at end of day.
