Oregano Oil? Tea Tree Oil? I have a drake with a marble-sized bumble on his "heel". I have read all the suggestions on this site for treating bumblefoot, but wanted to see if there's anyone out there who has used the oils mentioned above as I have them on-hand and I know they are effective anti-bacterial, anti-viral and anti-septics. I have read these arer safe for ducks, but would like to know how others have administerd using them? I am thinking soaking in warm water using one of the oils then applying topically with coconut oil?
