I have surrounded my entire run with 2"x4"x6' welded wire. Around the bottom of the run I put 36" hardware cloth, about a foot of it laying on the ground and covered with about 4" of dirt and running up the fence as far as it would go attached with zip ties. I also used the hardware cloth to fill in any gaps around the run where I thought anything might try to get in. My son even thought it might be a good idea to bury a piece under the ground where the gate is so we did that too. Here is my question. I have so much of this 2"x4"x6' wire left would it be okay to use that on the top of the run or do I need to go and get more hardware cloth for that as well. I will do whatever it takes but I am thinking this wire will be okay. What do you think? Can a hawk or raccoon or owl get through that wire at the top?
