I’ve used bone meal in the garden, but never fed it to deer. We used to put a lot of calcium out though, and the deer ate the heck out of it just like they did the salt licks.

One thing I found out about it and fish emulsion both in the garden though is something seemed to like it. I’m not sure if it was a coon or what it was for sure, but something tried to dig up all of my plants that were fertilized with either one of those.
