My neighbor called me this morning, her grandpa has a bantam chicken wandering around his backyard. No clue as to where it came from at all. Nobody claimed it in a door to door inquiry. So we have it in our old coop for now (for medical quarantine and acclimation to our existing 4 hens). She's a mild mannered little thing with a good appetite. (I hope it's a she, no roosters allowed in my neighborhood.) The black feathers have a blue/green sheen to them in the sunlight that shows pretty well in these photos. Any idea of the breed or gender?
