The domestication project was a project we did in biology. It was learning about behaviors of domestic animals. We all could pick our own questions to study. My question was how does the age of a horse determine training difficulty? I picked it because what I do is work with horses and I wanted to know if age affected anything. Well it does the older the horse the harder to train. I collected my information or data by training the horses. I did series of training sessions on two horses. One yearling and one two year old. The two year old was the hardest. My future question is why does age affect training?
