Fruit trees

They take long time to grow but give more fruits than crops continually , they can be farmed by birds picking fruits and there are 3 different types of trees:

1. Apple trees: the smallest one found in oak forest and similar to oak tree in size.
2. Walnut tree: the largest one found in taiga,it is as tall as mega taiga trees in its full growth, this tree takes very long time to grow but on the other hand it gives huge amount of walnuts, this fruit similar to potatoes when cooked gives way much hunger points than eating it raw, also it is farmed by the taiga crows.
3. Orange tree: the middle size one found in oak or jungle, oranges give 4 hunger points but when combined with diamonds they will cover each heart iqon the player has (2 hit points) with diamond heart iqon as shield (1 hit point).

These trees are found as saplings in their biomes or young trees in need of nurture and care to grow, by placing fertilizer blocks and water around that tree in certain radius.
