I am having an issue with reoccurring bumble foot in 2 of my hens. The vet recommended replacing their roosting bars with natural branches. They have been having problems since we changed their roost to 2x4’s. What is common to use as a roost? Our old coop had a round wooden dowel and we had no issues with Bumblefoot. I’m not sure how we would attatch tree branches/sticks inside of the coop, but would like to change to something that doesn’t cause this issue. Thanks for any input!
