The open wound will of course be of major concern, as it heals it will like with us humans feel itchy at times for which the mice will do anything from scratch to biting to alleviate the problem.
A antiseptic cream used for baby nappy rash is a good way of helping to alleviate that annoying itch and also help with killing any possible infection. apply using a q-tip as will a saline solution prior to putting on the cream. The wound will heal in time and regain full health providing no secondary infection occurs, however the area that the skin is missing depending on its size may remain a bald batch but would not prevent the buck from mating.
