hi i have been reading lots about eggs and calcium carbonate i read on one forum about crushing up antiacid tablets in their food!! i have managed to source a food grade calcium carbonate in a power form my question is is it safe to feed them powered calcium carbonate and if so how much? Or does the antiacid tablets crushed in the food seam a good idea? could i add the calcium carbonate to their water maybe any advice on this subject would be great!!
