I have had my "girls" for only 6 months, so I certainly am a newbie, but here is what I have learned. I have 3 chickens on about 1/3 of an acre. Many people have told me I "can have way more" but I don't want them to destroy my yard. I figure the 3 will provide enough eggs, eat bugs and provide fertilizer. I put inexpensive fencing around my garden and lined it with bird netting and it has kept them out...so far. When they find a new plant they like, I put a cage made of chicken wire around it for a couple of weeks and they seem to forget about it and move on. It is kind of a game to keep up with their new tastes in plants, but with blueberries, strawberries, raspberries, vegetable garden and many perennials, I am happy with how this summer went. I will see how next year goes when they are in their second year, but so far, I can deal with the little damage they have done. Oh, I also have found 2 places they like to dust bathe and have let them take over those spots. They haven't taken on a third spot and it seems to be working for us all...no holes in the lawn!
