Well, ya'll can laugh over my high tech coal bin:
It's a corner in the tobacco barn. Poured foundation makes up the side and back. Some heavy poplar floor joists repurposed when they replaced the floor of the sanctuary in the really old Catholic church make up the third side. And I like the front open so I can come and go easily with buckets.
A ton of egg on one side:
A ton of lump on the other:
And I'm set for the year. Keep a pole axe and a coal fork nearby. Few chicken transport coops, a gin pole, extension ladders, the obligatory plastic yard chair for libation and contemplation time, oh and elevated brooder boxes for when I'm hatching/selling chicks in the spring complete the scene:
Oh, and a 1947 Willys CJ2-A to keep the coal company.
ETA: The floor under the coal is repurposed corrugated metal roofing. No rock/dirt in the coal, and it was FREE!
