Thanks Linda. That's kind of you to say.
I know how much I enjoy checking out other folks facilities and poultry related inventions, and it's nice to share mine as well. Actually, I believe I read about the food colouring in the vent idea on this forum, only a few years or so ago. It's real simple and works wonderfully to pin point individual hens' eggs.
This is my summer coop, which used to be a grain bin too. It's currently growing out cockerels and a few culls until I can get to processing them. Being round made it extremely difficult to work with and we ended up not insulating, much to my regret. On this coop we used a lot of materials we already had on hand – like the window/door trim. It’s made from an old, wooden swather head the previous owner of the farm left hanging on the shop wall. And the run is made from 16' 2x6's that used to belong to an old deck on the back of the house. I love to be able to reuse and recondition items. Especially into chicken related items.
this is what it looked like before, minus the windows - "old grain silo full of old moldy grain, dust and mouse turds” pretty much sums it up, lol. I was going to attempt a gazebo type run with the other bin, but it was in such poor shape we just ended up ripping it down and burning the works.
Inside...is set up so the entire building can be divided in half with a removable wall if necessary. There is an enclosed pen on the north side, (very handy for integrating new birds, or for time outs if someone is being an ass) and dual roosting locations on the south side.
Outside in the run...we designed it so strategic roof panels could be added at a later date, but I've since discovered a tarp works fine and is a lot more affordable.
and the connector tunnel
Thanks for letting me share.
