Something appears to be getting into my coop at night, in spite all my efforts to make it predator-proof. Two mornings in a row now I've found a trail of feed from the tube feeder to the edge of where the coop would be if it weren't raised two feet of the ground. No birds have been harmed; the sliding door on the coop shows no attempt at getting in, and I've found no holes where anything entered from outside the coop.
Hopefully, I'll find out soon enough what the culprit is; I just hung a trail camera outside the end of the run. Never a dull moment...
