I will start off by saying that I only made it this far in the thread. I want to point out to properly run an experiment, EVERY factor must be controlled. This means they must have the same daylight hours, same water, same health (no mites, lice, bumble, etc) exact same amount of stress, etc. The only that can change is the feed to be 100% sure it's the feed causing these issues. If you run an experiment over a course of time when the daylight hours are shifting, your experiment is void. If you change their environment to only artificial light at a certain strength for a given amount of time, to ensure it feed not light causing change, the change in their environment alone would effect the legitimacy of your results. This all makes sense in my head. Maybe some else could reword it to make it more understandable
