I have been raising two chickens since this may and went to do the morning routine today and found one was missing. Upon investigating there is no evidence that there was a predator attack. There are no feathers, no signs of forced entry, no holes or gaps at the bottom of the coop or run area. They were in there just fine last night. My coop is relatively visible and in a high traffic area with no locks or anything to keep people out. Being the naïve person I am I never assumed that I needed to protect against theft. With no evidence of a kill or anything are humans more than likely the cause of my missing chicken?
