My friends and I do it. We usually incorporate it with some pigeon killing for the farmers that let us hunt. That's a riot!
We'll stop in and ask permission to crow hunt, go try to bust a few of them then stop back at the farm and roust the pigeons. Nothing like standing outside a silo and having a friend inside yell out "Get ready! There's like 2 dozen of them in here!!"
When we say we'll shoot pigeons (or just stop specifically to shoot pigeons) we've NEVER been turned down. Farmers hate them!
