Should be an easy fix for you taxidermist. I feel for you. I called an exterminator once to spray for bugs at a new house that I bought. All of my mounts were on the floor including a full strut turkey and three fan mounts and two deer heads. To make a long story short, all of my fan mounts were soaking wet with bug spray and the wings on the strutter were soaked as well. Needless to say I came unglued. I made one phone call and the owner of the business came out and my service was free. It was a simple case of neglect and laziness. But, in your case it sounds like it was an accident.
