I thought this might be a good place to ask. I am nearly done building the yard for my chickens, and I want to make a merry-go-round. I have seen them on you tube, but none of the instructions show what to use to keep the tire up on the spindle. I have several tires to choose from (2 wheel barrow tires, and 1 lawnmower tire), and a piece of rebar for the spindle. But what do I use to keep the tire above ground so it can spin? I have several other ideas of things they might enjoy. They have been cooped up nearly a year without being able to play outdoors. I have odds n ends of things laying around, I just don't know what to use to make it work. I have 8 hens and two baby roosters.
