I got brought a sick hen this evening. She has bumble foot on both feet.

On the worst foot the scab has come off and the wound has healed over leaving the core in place which is now infected and swollen.
I explained what needed to be done but I can't do it myself unless I took the hen for a few days and in my current living circumstances it isn't possible.
The owner took the hen to a vet and all the vet did was prescribe antibiotics.
I've got another sick hen coming on Thursday. From the sound of it she has an ear infection. I can do something about that.
