Well then it’s equally likely that badgers the size of Earth could be forming from time to time, and since they’re the size of earth they would decay much more slowly than our puny local badgers… so shouldn’t we see the occasional Earth-sized badger through the Hubble?

Or how about the much lower odds needed for a copy of Shakespeare’s plays translated to Klingon inscribed on a giant sheet of titanium to appear spontaneously? Far more likely to happen than a Boltzmann brain, right? So should we not have found an item or two like that?

If by "equally likely" you mean "much, much less likely, but also more than 0 probability" than yes.

Take another look at the time-frame on the GP's comment and remember that the Universe is ~10^13 years old.

Gotta be honest it doesn’t look a day over 10^12 years old when it’s sober and had a good night’s sleep

What Hubble? If you're a Boltzmann brain, the Hubble is just an idea you have in your temporary brain, before it pops like a soap bubble.
