Kwackers has had issues with rubber eggs for months. For equally as long I have been giving her Calcium citrate (she has always had oyster shell available). It helps a little, the shell gets slightly more calcified and then we are back where we started. I finally found Calcium Gluconate liquid (23%) at the store. I assume I give it orally, down one side of her throat, but I don’t know the dosage. Any help would be appreciated!
