I really doubt it being a bear....doesn't sound like enough damage, and they can get thru doubled hardware cloth. I also doubt it was a cat of some kind, because they kill to eat. I would say it is either 2-3 dogs in a pack....or feral pigs. I don't think it was a coon, because one coon wouldn't go thru the trouble of getting into 2 coops just to kill....they would get into one and kill all that was in the one and eat what it wanted....and they don't run in packs. Just so ya will know, ya do have panthers and bears there....they may not be nunerous, but they are certainly there....and feral hogs are becoming a major problem across the whole southeastern US and are horrible in Arkansas and Texas and spreading.
