I look forward to your next update & pics! Hopefully Ro will start healing well...maybe a plug will come up & your can get that out of there!RN, thanks for the advice on Ro, I will see what I can do about giving her an epsom salt soak next time around. And I agree on the 3 day bandage change schedule- we will definitely be going back to that.
IW- I think the cause was most likely a too-high roosting bar, at least initially. That has been addressed. Another contributing issue is probably the area that they free range (somewhat rocky ground, meadows + forest edges that have raspberry brambles and other assorted prickery growths), but I don't see any way for me to control that absent not free ranging them at all. Right now, I'm not willing to never let them out. I will continue to monitor their feet after this incident is resolved, and if I end up back in this position, obviously I may need to reconsider. I'm hoping it won't come to that.
It does sound like the free ranging & terrain might contribute to the bumblefoot...but this is one of those situations that you have to really look at the pros/cons of free ranging vs risk of injury. It sounds like you have done that & are willing to take the risk & let them out. There are no right or wrong answers here, only how you respond to the risks. Going forward I feel sure that you will take foot checks very seriously and be very aggressive in treating bumblefoot, as you have this time!
You have done a great job!!!
