could have been a few things, itl be back .. main problem around here is racoons, they will move lots of dirt, climb anything, and search for weak spots in a structure, theyre good at it, its what they do for a living ... but whatever it is coon, fox, bobcat, etc, the question is how do you get it .. doesnt ultimately matter what it is, it eats chickens lol, and your strategy will be the same .. knowing what it is isnt a factor in solving the problem, if its a night predator ... you have 4 options or a combo of them - poison, trap, reinforce your structures, or shoot them with a nightvision equiped weapon .. takes alot of strategy and 100% focus to be effective with a seasoned predator thats been honing its skills for several years .. everytime its been 'missed' its gotten that much better, so your plan has to work the first time lol, no room for mistakes .. set it up, and take it out, heheh
