Have you ever picked up a piece of wood from the ground in a shadowy place in the garden and noticed the lots of insects and worms wildly crawling around beneath it? Why not do that on purpose for the chickens? It seems to be called a “chicken board” and it’s as simple and as unremarkable as that.
Well, as you can see, mine is not exactly a “board” but any flat item of reasonable size will do. Just place it on the ground in a shadowy and damp place and move it every 3-4 days, revealing the accumulation of delicious treats below. Your chickens will love the all-you-can-eat buffet of yummyness served to them!
