Well I have had many chickens in the four years since I have first gotten my first batch of chickens. What I would like to remind everyone- especially some of you that our new to the "chicken" thing is that when you are building it make sure you are using small gaged wire- it is more expensive than regular chicken wire but anyone will tell you it is worth doing so in the beginning because you will end up having to change it later probably. If you cant afford to fence in the whole coop this way at least apply to it the bottom half of the coop. You make think there is no way that any raccoon or coyote or wolf, hawk etch will get in. After four years of having chickens my opinion has changed. Any little hole no matter how high will probably be breached by some animal sooner or later. I have seen fox jump up to five feet high and get in by some small little opening you would think would not be breachable. I also recommend applying the fencing to hang down at least 6 inches or more on the bottom. This will help prevent animals from digging under your fence line. That is one thing I am glad I have done. If you are making a run make sure you cover the top completely. Using chicken wire will not protect your animals. If an animal is determined enough they can chew through it!!! It amazes me still how year after year when an animal is determined to eat they will find away in!!! When you are building your coop make sure you spend some time constructing it as safely as possible. The most devasting part of owing chickens is coming out in the morning to find one or more of your chickens ripped apart or missing because of something you could have prevented! Everyone that has chickens will tell you that when building your coop it is not cheap if you are doing it right! If you are thinking of owning chickens please seriously consider this- they are lots of fun to own and it is nice to have your own eggs but it does cost some money up front. Just thought I would pass this along because I recently lost another chicken because of a small 4 inch gap on the corner of the run that was not completely enclosed. This little gap had been that way for awhile now and I never had a problem. But like I said sooner or later they will find away in. Do it in the beginning and you will be happy you did. Best of Luck with your chickens!!
