My 5 girls slept in their coup for the first time last night. I have a 4x8 ft pen for them to play in during the day. They got used to being outside about 3 or 4 times before I had them sleep in the coop all night. I just went out to scoot them into the coop for the evening (they don't go in by themselves yet) and this fox was laying there just staring at them. Of course he took off when he saw me. This is not good!!! I have the 1" chicken wire around the pen and on top of it I put the stronger 2x3 inch wiring. I buried the chicken wire 6" into the ground and 6" out so that if someone digs, they'll hit the wire. I put two 4x4 beams side by side all the way around the perimeter of the pen to help keep anyone from digging. Seeing the lousy fox staring at them tonight has me worried. How aggressive will he be when I'm asleep and he's hungry??????
