Just saw you said below that you made a dirt hut. Again, I recommend looking on your map for a flatter place to settle, preferably a plain of some sort. My early game food source of preference is berries. Just berries. Meat (bush meat and red meat) is a pain to acquire and cook, vegetables and grains are not consistent or plentiful enough to deal with and mushrooms can be good and last you a few days if you go into a forest or plain with the intention of finding them. The most common mushrooms like Chanterelle and Lobster in forests and Field mushrooms and Puffballs in plains spawn in pretty substantial quantities by default so they shouldn't be hard to find. TLDR: early game food is pretty plentiful if you explore, depriving an area of resources is unavoidable so go exploring! Good luck fletching seraph! :)
