Well, after the eBay fuss I bought some catapult latex/elastic straps and searched hedges for a decent stick. Bingo, a windy evening and the next morning I was spoilt for choice. You need there to be a symmetrical Y shape in the wood, if it’s wonky it still works but the aim is all wrong. Sawing the branch into a Y shape. Yes, I know I know, chicken runs are not ideal work benches. You need to cut the “handle” end to be about the length of a brand new pencil, and the two angled branches a little shorter.
My bunnies went down the vet for the snip, poor things. But yesterday was home time, so until healed a bit I have them in an indoor small hutch as I don’t want them to get mud on their scars.
