Grandma Duck lives on a farm with many acres of land, given to her by her father Clinton Coot, outside the city of Duckburg. She is very strict and punctual on how to run the farm efficiently, like always getting up very early in the morning to have time to do all the chores, which is an attitude not shared by her great-nephew and farmhand Gus Goose. Gus is very lazy and doesn't do much work at all, spending most of his time eating or sleeping instead, but Grandma is very patient with him and lets him stay on the farm anyway. In some stories, especially older ones, Grandma Duck also gets help from Gus and Jaq, the two mice from Cinderella. She also has a number of farm animals; including Billy Goat, the cows Bossy and Queenie, a bull named Angus, the hens Eggatha, Steady Heddy and Henrietta, and a horse named Dobbin. At one time, in Carl Barks' story The Whole Herd of Help (1961), she is even given an elephant named Packy by Scrooge McDuck, mostly because he wanted to get it off his hands. Grandma also has a few distant farmer neighbors and the most notable is farmer Si Bumpkin, a tall anthropomorphic chicken, who is easily annoyed when he in some way is affected by disturbances on Grandma's farm, which often caused by her family or friends. Her farm is also the center of the Duck family's annual holiday gatherings, with said gatherings usually arranged by her, and these are always merry, warm and interesting occasions, greatly appreciated by her kinfolk.
