You were told a load of crap. I had an agent tell me the same thing..."If you want to wait another 3 hours while I get a warrant we can". I said yes please, I will wait. A warrant cannot be issued without probable cause, and you denying search and seizure is not grounds for probable cause. I called my warden's bluff and he left without incident and of course never returned with a warrant. The Showers case spells out the differences between search and inspection. It doesn't matter what they say you are required to do under your license. State law does not supersede federal law. You have rights as a US citizen that states cannot take away. They can inspect your records. They can ask to see a specimen to make sure it matches your records. They cannot search your freezers, storage areas, closets, or even your medicine cabinet. If the story you related is true how you told it with no facts missing, that taxidermists rights were violated.
