chickens on the loose

So my partner I have moved to a fixer upper of a rental home.  The fact that we are paying rent while others in combination with the two of us are working to make the house livable and look decent kind of sounds ridiculous.  However, the house is on 5 acres, the landlord is very understanding, and we are able to knock off $100 in rent per month for the foreseeable future.  Lets not forget that we now have 5 acres to play with as well.  This means the original chickens are very happy and that we can now have quite a few more....  Not sure exactly what the few more looks like right now but the hope is to sell some eggs and maybe even some whole dressed birds.
