Rather surprising fun fact: in many years, the top export of George Washington's main plantation Mount Vernon was not tobacco nor any other cash crop, but fish.
This is less of a specific fact and more of a point, but I had a misimpression that slaves were taken care of by their masters, and I think a lot of other people probably would.
The way American slavery actually (usually) worked was that a slave would receive a cabin, a single set of clothes a year, and some basic rations, like bags of cornmeal or rice, possibly bacon if they were lucky (but not necessarily), and the offal from animals slaughtered for the White folks (which is where things like chitlins come from). Additionally, slaves tended to be treated to a feast at Christmastime and given liquor, which sometimes was banned otherwise.
This was generally not enough to feed a slave family through the year. They ate very little meat, but would tend to be allowed to keep chickens, and their veggies usually came from their own gardens. Often slaves worked a fairly short work day (by modern standards) for master, like say four hours, but they spent pretty much the rest of the daylight working on their own gardens to produce their basic foodstuffs.
So slaves did receive rations, but it's not really correct to think of their master as feeding them, because the rations were like a bare subsistence diet that the slave supplemented through their own work. Often garden plots and livestock would be handed out as rewards to productive slaves.
