FarmVille Animal Mastery Slowly Rolling Out

So the Slow Roll out of Animal Mastery has started. 60+ Pages of Animals with 8 animals per page. Calves and foals do not seem to be masterable at this time. Some animals are very quick masteries, some will take 100s of harvests.

I think its over 30 Plots worth of New Mastery Signs, if they are all mushed up together.
