No…..my premise would be that coyotes came in gradually and moved the needle in the 5-10% range over time and the additional predation pressure on the landscape is why we have seen a gradual decline that is fairly moderate in scope……A disease outbreak caused by the sudden addition of corn feeders and corn piles would move the needle a chit ton…..not just a little……If aflatoxins in corn piles are a problem then they should be a big problem and most of the flock gone…… not a gradual decline…….more like a bottleneck
