So I decided to tan a coyote for the first time and it hasn't turned out great. I skinned it pretty good, getting everything but the end of it's nose. I double bagged it and put it in the freezer for about a week and a half. Got it out and washed it in Dawn soap and fleshed it and pulled the cartilage out of the ears. Then I salted it and rolled it up skin on skin and let sit 24 hours. Scraped salt off and covered it in salt again for another 24 hours. Then I put in a salt bath for 8 hours and last night when I removed it it had blue spots. Not everywhere just on the ears and one spot on the belly. I cut the ears off so they won't be an issue. What did I do wrong? I got salt in every nook and cranny.
