I have an area that is about 50x50 and it has about 6-8 dwarf fruit trees I am just trying to get started. I plan on putting 6 foot chainlink around the perimeter. I was going to put an old picnic table in it for the chickens a little protection. I was planning on keeping quite a bit of straw over the ground, the area is slightly sloped-not a lot. But it is enough that it may wash out a little over time if all the grass were gone like I planned. But now I am wondering if the chickens would even kill out the grass in an area that large? I plan on getting about 12-15 chickens and a rooster. I covet any thoughts or advice about my ideas. Obviously I don't want to invest of all this work time and money if it isn't going to work. I don't know hardly anything about chickens, I have never had them.
