Hi- Here is my first coup and I put my first chickens in there today. I am just wondering if I can get a little advice on the security of my coup. I put chicken wire all the way around the run and the front of the coup. The front I am a little worried about as there is not a board going across the front. Do I need to lock them up in the coup every night, or since I have an enclosed run they can go in and out freely. We have opossum and I am sure raccoons. Can they dig in there? I have an 8 foot fence around my whole backyard. Does anyone see any other additional problems with my coup? I added the bucket waterer and feeder after these pictures were taken... I have two chickens now. As a side note, how many do you think this size coup could handle. Thanks in advance.
