Hi, I have been keeping my 3 mellers in a free rang set up for over a year and they have been really healthy. Over the past 2 weeks I have noticed that the 2 females have developed ulcers on their hind feet and I have started them on injectable amikacin and topical iodine daily. I feel however that the wounds appear to be progressing despite treatment. I am unsure if there is any other treatment options? I am sure some husbandry issue is at fault, but I have setup everything as suggested on the melleri discovery website, but possibly increased humidity is at fault? Any suggestions would be greatly appreciated!
