I can relate to your attachment to your chickens. I inherited 8 from my neighbors when they moved. I thought they were just chickens but they have become my girls. I lost one shortly after getting them to disease and was devastated. There has been allot of good advise here on integrating new chickens with Fluffy. One other recommendation I would make is to ensure you spend some time predator proofing your run/coop by installing a predator apron. I went overkill on mine but I am determined there is nothing digging into my girls run. Here is a picture of how I did mine. I used 24" Hardware Fabric with a second layer of Coated Welded Wire Fence
