Here's my two cents... and this goes for all animals, humans included. If creatures are raised and live in a vacuum without anything to get their hearts beating a bit, when something scary DOES happen, they are more likely to overreact and become sick or dead. However, if a little excitement is the norm, if life brings surprises on a somewhat frequent basis, they get past the little stuff and are stronger for it. If you were holding them upside down and shaking them to check if they were alive, THAT would be mean. But as they are being raised in a pretty sterile environment (in comparison to what they would experience say 50 years ago on the farm), I think you are doing them a favor... AND yourself. Personally, looking at your picture - especially the one with her legs STRAIGHT OUT- I would wake em up too!
