We had two silkies as pets contained in a shed with a chicken wire yard. We think a cat got into one of the smaller windows and took down our first beloved chicken - it simply disappeared and left behind a few feathers. Then two days later we found the remainding chicken decapitated with blood all over the chicken wire fence. The chicken was on the INSIDE of the fence. All the coops that I'm looking at have the same type of fencing. Any suggestions on how to make them more secure?
