As an insight, I have purchased SS horse feed and other products from Carthage Farm Supply. I know they have chicken feeds but don't know which ones. I have stopped in there to get other products when taking our dogs/cats to Carthage Animal Hospital. When the girls' were really little and we'd moved from Parkton to Lillington - Carthage was the only SS dealer at the time (2004) that we could find that carried the same feed that I'd purchased in Saint Pauls in bulk. CTC is now also a Southern States feed supplier, but they don't carry all the SS brands either...
I generally go to CTC, in Sanford, because it's easy, the people are great and I get the most "bang for my buck". I purchase horse feed, alfalfa pellets or cubes (not getting those at all right now), chicken and chick feed, rabbet feed, cat food (why is it food for one and feed for the other species?). Sometimes chicks & ducks, sometimes other products - buckets, tubs, dog/cat collars as they wear out, reptile lights for daughter's bearded dragon & chick lights, meds as needed - when I don't order them directly from a Vet Catalog, etc.
While in Sanford, I can make a bank run to a bank I can't easily access in other areas (PNC) and usually that is a pick up to go food dinner night for 4 adults and 2 children and sometimes more (before C19 - when the family did LARGE gatherings of adults and kids and spent hours playing D&D).
I generally get all fencing and large water tubs at
TSC - much less expensive and buy in bulk - except HC - which I get thru my hubbies link to
Amazon Prime.
