Love that bit about falling in a chicken coop. made me laugh a lotI've raised chickens on and off for 65 years and as this threads resident curmudgeon I often give advice that some view as harsh or callus. For instance, I don't believe in trying to find a vet that will charge you over $100 to try and save a $5 bird. Nor do I believe that chickens can be affectionate. Any interest they show in you is based on food. Plain and simple.
When introducing new birds to a flock, I always add them in the dark. Come morning they don't have the sense to realize there are new birds. I see no reason to spend days with them in close proximity in the belief that there will be fewer problems. There will be absolutely no difference. However, you may have some difficulties that you need to monitor. There will be some re-establishing of the pecking order. Often birds of a different color will receive quite a few problems with the more dominant members of the flock. Also birds of a much smaller size should never be added as they often are killed.
I know many people talk about how gentle and loving their birds are, but as a friend once told me, if you fall in a chicken coop they will eat you.
