Our coop sits right in front of a small grove of trees/brush. Our chickens would go in to roost every night until we found a rat snake in the coop the other week. After that, only 1 or 2 hens would roost in the coop and the others would roost in the trees right next to the coop. We tried "resetting" them by keeping them locked in the coop for 3 days straight and it helped a little (now 3-4 hens roost in the coop and the rest still roost in the trees). After that we noticed a hen missing in the morning. So we tried again for another 3 day lock down. After they came out, same story. 3 or 4 roost in the coop, the rest in the trees. We started noticing chickens missing in the morning again. I'm thinking its a fox but not positive yet. All that to say: 1) Would moving the coop away from the trees and locking them in for a few days help encourage the hens to start roosting in the coop again or do you think they will just flock to the trees anyway? 2) Would moving the coop away from the trees help deter predators since they would have to walk across a small but wide open field? Other than shoot the predator or keep them enclosed at all times, any other advice? Thanks!
