Okay, so we have to do a glorified science fair project. I want to do something with: chickens, bunnies, horses, goats, dogs, cats, etc. Oh, and my friend would like to do something with cavies. Unfortunately, it can't be a yes/no answer type thing (example: do peanuts in the diet increase a hen's production?) However, a study on various components in the diet would work just fine. (out of sunflower seeds, peanuts, and commercial feed, which affects the hen's production the most?) Anybody got any good ideas?
