Need your advice/comment. I bought a bunch of pre-inoculated mushroom spawn and, following the instructions, poked holes in one of my downed oak trees. I placed the plugs into the holes, some of them were sticking up out of the log by about an eighth or sixteenth of an inch, watered them, etc. I just checked them yesterday and it appears as though something (what?) came and pulled out at least half of what I had stuck in the log. What do you think did that? A bird? Some other animal? I'm quite mystified by it. The plugs that were flush with the top of the log weren't touched, just the ones I couldn't get holes in deeper.
