During health inspections today, I discovered one of my girls has a small spot of Bumblefoot. I'll be doing the non-surgical removal recommended by Tilly's Nest. In the article, she states the hen should be separated from the flock for a time and I want to know if this is imperative. If she stays with the flock, do I need to pad the roost? If she does have to be separated, how long? This is my first experience with Bumblefoot so I'm learning as I go. Thanks in advance.
