She knows about post death twitching, just was observing it's length.
IME, the sicker the bird being euthanized, the shorter and weaker the twitching.
I would agree with this and in addition I would add that the younger the bird is the longer it twitches. Older birds don't seem to go for as long.
It would be interesting to try and do a study: record age of bird, euthanize, record time of flapping. Perhaps it's all just in our minds, perhaps it has to do with some other factor. It would be cool to find out.
