I suspected you were from Colorado when I heard this, and looking at your profile confirmed it. I went there twice (luckily no bear break-ins) and we were keeping trash containers outside closed with heavy-duty locks, and making sure no food was left in the van. Unfortunately, I have no advice for keeping bears out of coops, and I’m sorry your flock was eaten (or died).Bear flipped over our coop. Ate 4 but 2 managed to survive. Sadly our pullets didn't make it. Based on the the tracks I'd say 175-225 lbs bear.View attachment 2655611
