Chelsea Farmers Supply was built in 1855 and is one of the oldest institutions in Chelsea. The business historically served commercial farmers in the area and, while it still does this, it also has greatly increased its hobby farmers and gardeners business. It has introduced many more pet supplies and feed items, especially for bird watchers. This store now sells farm supplies and lawn, garden and landscaping materials. It also sells feed and equipment for animals, from household pets to livestock and horses. Unique gifts also are available.
