Thanks! I thought it was her ear, but I've never seen one before and wanted to make sure!
She is eating a mix of radicchio, escarole, romain, endive, grass I grow for her, Grassland tort food, and some mazuri all mixed together. I have to combine a lot of flavors to hide the calcium taste. She doesn't usually get such a big mix like this but she is so picky about eating her calcium that every other day she gets one very fancy meal!
Is the calcium a powdered calcium? You should only add a little bit and they should not be able to taste it. You don't want to offer too much all the time, either. A lot of the food we buy at grocery stores are jam packed with vitamins and such that they would never have so much of in the wild.
I think she probably eats better than I do! I definitely spend more time and money finding good stuff for her than I do for myself!
The calcium is powdered and I don't use much at all, but she refuses to touch her food if even the tiniest little speck is on it, unless I hide it well. For a while I could use a little grated carrot as a special treat to hide the calcium but then she wised up and stopped eating it.
She has a cuttle bone but I've never seen her chew on it, and it hasn't gotten any smaller in the two months that it has been in her little house.
I had a weird cactus flavored cuttle bone in my tortoises enclosure for a while, she never touched it. Put in a normal one, like the kind you use for birds, she's all over it. Some tortoises like it, some don't. Sound like you've got it covered!
