Showing you my grit/oyster shell feeder I made today. The lid flips up to fill the tubes and is slanted to discourage chicken roosting. The wood is unfinished and all edges are sanded for the chicken's safety.
We have continued to plan the details of our chicken hen house/chicken runs. I had mentioned in an early post called Chickens - How Much Space? that I was looking at a design that involved 1 hen house, attached to 4 chicken runs/pastures.
