Yep. Ask your local game warden because he's the dude that will show up.
I don't think so. Its the fed that normally shows up for baiting, normally on a tip. I had a local GW tell me that and it makes sense.
Here is my take on this. There are 2 aspects to the baiting law. In general..
1) You cannot hunt migratory bird "over" bait, "over" is the key word here. So you cannot sit over a deer feeder and hunt migratory bird, period. So if deer feeder is on another property, and you are across the fence don't matter.
2) You cannot use bait as an "aid" to kill birds, "aid" is the key word here. The issue here is if the deer feeder is holding birds. If a deer feeder is not holding/attracting birds, it is not "aiding". And you are good. If it is holding/attracting birds, then this is an issue. Because if you are killing birds going to that feeder, and that feeder could be 10 miles away, you could get a ticket for this, especially if GW (normally a fed) has done his investigation and has built a case against you which normally they have, and can show you have petterned the birds and killing them on the way from roost to the feeder. When fed GW show up, you are getting ticket for something, they are not making a trip to your property to go home with no tickets.
I had duck lease for years, owner put deer feeders on it, I didn't like it, but they never held/attracted birds so I did not worry about it. If they held birds, then that would have been a problem.
