The color of feces is caused by something he is eating.
No it should not if you have green feces you have a medical problem you should tell an adult you trust and they will give you more information and (if necessary) help.
The red food coloring in (mostly cheap) red wine combined with the normal brown color of feces = green!

Penguin feces can range in color from white to green, depending on their diet. The green color comes from their consumption of krill and fish, which contain pigments that can give the feces a greenish hue.
Yep. Yellow and blue makes green (there's some yellow in feces from bile). Happens every time I drink an Ocean Water from Sonic.
Stools/feces are dark olive green, formed and loose for about six weeks.
You would be eating waaaay to much for that to happen.
