I am a newbie and I am trying to find out how to construct a pen using 4ft chicken wire and connecting it together to make the pen fence higher. Are there rings you can us or do you need to use wood to sandwich the wire together? I am trying to use what ever materials I may have laying a round. I don't have a lot of funds to spend on this project yet I do want the chickens to be safe. The pen will be 8x8 and the coop will be approximately 8x6. I haven't started yet. Also, I have a lot of rock and cannot dig deep, was wondering how far out away from the pen must the wire be barried? I really excited about this project and could really use the help.
