Today we rescued a hen. It is a long story, but a neighbor brought her home last night from a job site and told me he did not want it because he thought it was a rooster. I told him that she was just a very big (tall) hen. He left it wandering in his yard (out all night unprotected) and finally I offered to take her. She seems very sweet, but now I am not quite sure how to integrate her with our flock of 12 (11 girls and 1 rooster). She is much bigger then even our biggest girl, but I am not sure if that matters. She seems very passive. For now I have her in the coop and everyone else is free ranging. Any thoughts on what I should do when nightfall comes?
