I fell down a rabbit hole this morning researching some issue, and eventually found my way to a YouTube video for Carolina Coops. Fancy coop builders, they are! One of the coop accessories they provide is a roost bar wrapped in hemp rope - said to promote air flow around the foot, which might help improve bumblefoot treatment. Here's a link to their website: https://carolinacoops.com/product/rope-wrapped-roost-bar/ Now, they actually sell these roosting bars, but the shipping is as much as the bar, so I thought maybe I could DIY... Think it would be worth a try? And more importantly, 1/4" or 3/8"?
