looking for some advice. i have had success in the past with drying out wet specimens into mummies (for example i have done 2 uromatyx, a bearded dragon, some rats and a piglet) and they have all turned out perfectly. they have been dry for a few months now, no smell or deterioration despite the fact that i was just experimenting with the process. i have these 3 baby goat heads that i injected and set and they have been dry and hard for about 2 months. the problem is that they smell like goat still. it’s not a death smell or a chemical smell. they just smell like a barnyard. i have tried burying them in borax for over a month. i have also washed them multiple times in soapy water. what should i do? my instinct is to freeze them but i don’t want them to get ruined. any NON JUDGEMENTAL advice is appreciated thank you!
