Paul Wheaton and Jocelyn Campbell discuss Paul's article about raising chickens in detail. In the very beginning Paul mentions his site for java programming. Paul discusses a ranking system that covers several ways he knows to raise and care for chickens.
Paul also covers a metrics system. Each factor has a number scale. 0 represents sucky. And 10 represents awesome.
The factors are:
1. Poop factor. Actually this can be broken up into 2 factors. The amount of poop I have to deal with and the amount of poop the chickens have to deal with
2. Vegetation factor. How much fresh vegetation can the chickens browse?
3. How much feed cost is there?
4. Bug factor
5. Time factor
6. Freedom factor
