So we had a large party here last weekend and as a result I have egg shells all over my yard and I mean all over. I have been out of town a few days so today I am out cleaning up. I have both my Russians out enjoying the day with me. I noticed my female is eating the egg shells. I took it away and she got mad. The male has no interest but she is hunting them out. Should I be concerned? I assumed that meant she's craving extra calcium, even though she gets supplements every other day and has cuttlebone access all the time. What do you think?
