drowning is not painless. It's rather quick (unconscious within minutes) but drowning itself is very painful, hence the bodies reaction being rendered unconcious.
Ha! You're both wrong. Been there, done that. Its pretty peaceful, aside from the struggle to survive.(Bee gathers her chicks close and whispers, "It's alright...shhhhhhh...it's alright....don't listen to her!")
I've seen death by drowning and it ain't peaceful...not even a little bit. I think I drowned those chicks in Nest 3 when I added all that humidity...wish I hadn't done that but it probably doesn't take much to drown a chick, huh?
