Bonemeal Powered Wool Farm

Produces up to 3500 wool blocks per hour using 1.21.5 mechanic that allows sheep to regrow wool by eating the dry grass which can be produced by using bonemeal on tall dry grass. Small footprint and cheap material list. Rates are dependent on the number of sheep in the farm with a max being 48 (24 in each of the 2 1x1 shearing stations). Mix and match whatever color of sheep you want. Note: This requires using a piston to push a grass block down onto a hopper minecart. To do this point two hoppers into the barrel at the bottom and place rails on the hoppers. The place the hopper minecarts on the rails and then carefully break the rails (carts should drop onto the hopper then in the block above the minecart place a dirt/grass block with a downward facing piston above it, power the piston and you are done.
