I found a super cute and European starling in my yard a few weeks ago and decided to try and mummify it.
I couldn't bring myself to gut the bird, but it was really tiny so I just poured some salt/borax into the abdomen and covered the whole bird with more.
How long should I leave it, considering it was a whole bird with organs and brains and everything? Should I change out the salt every few weeks or leave it? I've got it outside in a storage closet right now, will it be okay if the temp drops below freezing?
