So recently I was trying to find some old studies I forgot to bookmark regarding high calcium fed to cockerels, but instead ran across the subject of carbonated water as it effects birds in hot climates. I thought I would share these with the group. Now mind I'm no scientist and I didn't even properly finish high school, but from what I can make out they seem to suggest that carbonated water could have beneficial effects on birds who are getting hit hard by hot weather.
