simple translation of simple text and question about 个 and 自己
This old rabbit/goat story is an allusion to North Korean politics， right?

1。他有见兔正给山羊来送白菜。 


He saw the rabbit give the goat a cabbage.


2。我自己种的。只有自己种，才有吃不完的菜。 


I planted them myself. If you grow your own veggies then you will always have enough to eat.


Edit 2。 '我自己种的‘ could be written '这棵白菜是我自己种的‘，Chinese likes to shorten sentences. I'm not paranoid, I know they do it just to confuse poor me!

我自己种 = I myself plant = I planted (them) myself.

自己 = self, myself, yourself, themselves, depending on context.

3。青菜萝卜吃个饱 


I'm full up with chop-choi and carrots. (this must be Kim Jong Un, the 胖子)


吃个包 = eat a fill = eat until you are full
