Stew meat. ;) Old chickens don't actually have any special nomenclature. "Pullets" are young, immature female chickens and "hens" are mature, female chickens. However, most hens will continue laying until the year they die, just not nearly in the quantity that they did when they were 1 year old.
Yes, it only takes a few days for the chickens to know where they live. The rooster will call the hens home before dark if you have one, but they almost always find their way to the coop even without a rooster calling them home. When new hens are introduced to the flock they sometimes try to roost outside the coop the first night until they are used to the pecking order (who sleeps where).
The plural form for the noun chicken is chickens; the plural possessive form is chickens'.
