I was on vacation for a little over a week and my sister was watching the animals when we came back we relised that 2 of our almost full grown chicks were gone we searched for them and later we found poop in a corner were they may have escaped and taken shelter for the night. We never did end up finding them but again later that day we relised we were missing another chicken we found her fethers everywhere we thought it was a hawk because there was no fur in the fence like an animal may have squeezed in and the fact that it's protective for ground predators. The next day we let the chickens out and I went back inside for a little bit. I came back outside to check on them and there was more feathers where the last chicken was killed except different colors of feathers and there was another missing chicken
