Beside having berries and apples who can be both looted on bush and threes, it would be nice to have more source of food gathering who not require any kind of tools such:

• mushroom spawns into the wild (like 5-6 different kind some comestible, some who can poison you).
• eggs randomly available with low drop rate (something like 10%) into hen houses (must be cooked, otherwise the player could have a little chance to vomit, but not sick).
