Need EVERYONE'S Advice please help

The farmer leased it directly to him on my recommendation and I recommended him after having several conversations with him. After talking with him, it was clear he knew the right way to hunt. So, now I know that he was full of &*%$ and that he just talks a good game but acts like an @$$. The location of the blinds is not the issue as with a wind from his direction he can't hear me and vice versa. And we have had birds flare from shots from 3+ miles away if the wind is from that direction. I don't mind birds flaring if he is making legitimate shots at birds but the shooting of everything that passes after I have talked to him politely considering I got him in the lease.
