Many people have stopped going to secondary if primary fermentation is less than a month. If you are lagering for extended periods then a secondary should be used.
After a month, your beer should still have about a million cells per milliliter, unless you cold crashed it (35-40F).
You cannot see a million cells per milliliter.
Why add more yeast? Are you not reaching terminal gravity? It is generally better to warm the beer and keep it on the yeast to help it finish out.
>Also what is the stance on using yeast energizer and yeast nutrient in beer brewing?
I generally use Wyeast Yeast Nutrient, but I forgot last night! You are right that it is more needed in mead since honey doesn't have much of what the yeast needs to grow new cells.
>And is there anywhere I can read about or watch a video on how to rack to a secondary?
Yup. Here is Michael Dawson from Northern Brewer. He racks like a champ.
