We have had one two-year-old hen for the past couple months. (She was a hand-me-down and has yet to lay an egg...but that is another story!) We are buying two or four mature hens (coming in pairs) and would like to keep them all in the same coop and yard. Everything I have read about adding to a flock is in reference to an existing flock with multiple hens...obviously, with only one hen, we don't have a pecking order to worry about. Any tips on merging them all together?
