In the previous practical session, you created a full (albeit simple) NetLogo model of some sheep eating grass. In this practical, we will improve the realism of the model and add some new functionality:
Before getting started, make a copy of the NetLogo model that you made for practical 2. In this practical we will improve the realism of that simple model, but it is worth copying it in case you want to go back to the original at any time. The easiest way to do this is to simply copy the file using Windows Explorer.
When you have done that, move on to the first part to begin.
