It's funny you say that...I just had a conversation with a collector about that. Some of my sheds have nibble marks on the tips only and he thinks that is from deer. I guess that the guys with pinned deer say that they see other deer chewing on sheds. I don't think they actually eat them, just chew on them a bit. I found that interesting.I think the big deer eat their own sheds.
I pick up the little sheds and usually shoot over the top of the big ones.
