Above you see something that it's hard to find on any other Web site on the Internet. It's a fresh pile of chicken feces, also known as chicken manure, chicken poo and by other names. It's about the size of the last joint in your thumb.
The nice thing about this picture is that it so clearly shows the white, pasty stuff on the right side of the dropping. That white paste is composed mostly of uric acid, and here's the story about that:
Every second of the day and night, animals are producing waste products inside
their bodies. If those waste products are not removed from the body, the animal may become
ill or die. One of the most dangerous of all such waste products is the chemical resulting
from the normal breakdown of amino acids (which make up protein) and nucleic acids (of
which our genetic material is composed). The main waste product formed during this
decomposition is ammonia, NH
In mammals such as us humans, our waste ammonia is combined with carbon
Unfortunately, urinating is fairly wasteful of water. Reptiles and birds have developed
a different, less water-wasting process for dealing with their bodies' ammonia. Instead of
converting their ammonia to urea, they mostly convert it to uric acid, C
It seems that birds and reptiles have developed an ammonia-disposal system that in many ways is better than our mammalian system. If our bodies could convert our ammonia to pasty uric acid instead of urea, we wouldn't have to drink nearly as much water, nor would we have to go pee nearly as often!
