I lost too many of my dear chickens last year. In the fall my husband built a large chicken coop which I have kept them sequestered in all winter. Now that spring is here we have to decide how best to protect them when they are in the pen. The pen itself has an electric wire running about 2 feet off the ground and again on top. But never the less something continued to get in and kill them. Sometimes the whole chicken would be gone. We caught many possums but I also believe a chicken hawk was getting in through the top during the day and killing and/or taking them. I've heard that the mesh that you can use over the top of the pen doesn't work all that well AND our penned in area is huge. Are there any animals that are safe to raise in the penned in area along with the chickens that would help keep predators out? We've thought about two goats but aren't sure that would do the trick. Can anyone help?
