“Today when I picked them up I noticed each has kind of a soft shell, both the top & bottom yeild a bit to gentle pressure from my fingernail.
I don't have them under UVA/UVB, but take them out for natural sunlight at least once a week. I used to have them under UVA/UVB lights but moved their enclosure & realized they spent all their time under cover during the day anyway. I supplement every feeding with Sandfire Box Turtle Dust.”
I realize this point may already have reached closure. However the ambiguity of much terminology and the strong possibility of misunderstanding the calcium / phosphorous relationship merits concern.
Soft squishy shells? Pliable under pressure? These can mean many different degrees of shell hardness. To the individual that presses hard or to the individual that presses softer, and fifty degrees in between; these well meaning descriptions can be misleading especially to one who is asking and inexperienced.
Also if your young boxie does have a soft shell; pressing frequently is very risky during this vunerable time.
It is important to know when answering this question the age of your boxies more precisely ( in months). I realize you stated ....Under a year. But that leaves much to speculation. A boxie at four months or even six months will have a very different shell density when compared to a boxie of nine, ten or eleven months.
* Approaching one year of age; a boxie‘s shell should be unquestionably solid. In regards to the amount of natural light; once or twice a week is far below it’s needs of daily exposure to UVB / UVA light especially at such a crucial growth period. Comparing the light it would be exposed to in the wild; even under brush, and cloudy days; is 30 times more than the common 5% UVB artificial light.
* All calcium dust and reptile vitamin dust is not the same. *
You want to try and use a powder that is very high in calcium to the ratio of phosphorus. Using a powder that contains both in boxies will lock up the available calcium due to the high amount of phosphorous in a captive boxie’s diet. Crickets, and mealworms for example are very high in phosphorus. Understanding the balance is the key...
*Calcium is but one link in a Boxies health. The other two elements are Vitamin D3 acquired from Ultraviolet B light, and Phosphorus. An imbalance in the link will cause :
- Too much D3, calcium, or phosphorus**Hypercalcemia.
-A lack of D3, calcium, or phosphorus****Hypocalcemia.
-So too much phosphorus can throw the balance off as well as too little D3, or too little access to Ultra B wavelengths.
At the very least; I suggest increasing the amount of natural light.
*** While your boxie may be avoiding your artificial light; there are reasons causing this reaction. Already failing to reply with brevity; I will respond if asked via a separate email.
I absolutely loved your pics. Those are some of the BEST!
