<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">As part of our museum move, as a precaution, we recently froze all of our exhibited taxidermy before moving them into the new building. We treated 7 small specimens, mostly
birds, in a chest freezer and 13 large mammals in a rented reefer unit, both at -30C. The specimens are various ages and conditions. No damage was noted. I have also routinely frozen taxidermy in the past with no problems using the guidelines Dee linked
to. I think as long as your birds are not in a high humidity environment before going into the bags, you don’t need to worry about moisture.<o:p></o:p></span></p>

live pests and prevent their spreading, and it helps to protect the specimens during the freezing process. You may find the following two resources helpful as background reading. Do be careful handling any frozen specimens as they are more vulnerable to physical
damage while frozen because many materials are more brittle while frozen.</span><span lang="EN-CA"><o:p></o:p></span></p>

in the past with success, but I'm feeling a little more nervous than usual given the importance of the specimens.

<p class="MsoNormal"><span lang="EN-CA">In the past, I had been trained to wrap specimens in airtight bags before putting them in the freezer. Does anyone know the reasoning behind this? I was told it was help to prevent condensation but I'm almost more afraid
of trapping moisture inside the bag. I'm wondering if I can get away with putting them in an airtight storage container or even leave them exposed to avoid handling them more than I have to.
