I have a 6 month old horsefield tortoise. I sprinkle his food three times a week with calcium powder. I’ve noticed that when I do he’ll try and bite the powder off his feeding slate first rather than go for the food. Once I sprinkled a bit too much in and it formed a small pile on a leaf and before I could grab it, the tortoise had stuck his face in and was eating the powder rather than the leaf! Yes, there is a fresh cuttle fish bone AND calcium block in his enclosure which he never touches. He eats, poops and pees normally and is very active and normal in every other way. Is this something I should be worried about or just a normal tortoise quirk?
