Based on everything I've read here, our chickens should be safe for the most part. The bottom 3 feet of the run is doubled up with 2x3" welded wire and the top is covered with brightly colored string. The pop door will be closed every night as well. Are we in good shape or is there still room for improvement? Also, since I have electric to the coop, would a motion sensor lite discourage night time visitors such as coons and coyotes? I might install one regardless as it would give me an easier shot with the .22 mag from the bedroom window... It's worth noting that my neighbor has 17 chickens and all he has is poultry netting 6 feet high with nothing over the top and hasn't lost any chickens so far. Thanks for any input.
