I have been keeping two hens in the suburbs for a while, and I just lost one. The one hen that is left, a RIR, just over a year old, is doing pretty well so far alone, just a little jumpy, but I imagine she will be happier with company. Is that what you've found, or can a chicken be happy alone? If I do find a new hen to add to the flock, any advice on how to incorporate her? How do I make sure they won't have diseases to pass? And is there any particular breed you'd recommend or avoid with a RIR? Thanks!
