Regardless, wilds squirrels seem able to balance their calcium needs better than we humans are able to manage captive squirrels, dependent on the foods we provide, at least IMO.
The true key to calcium is not as much ensuring they eat enough calcium, but ensuring they are not getting too much calcium robbing foods in their diets. And the increased activity of a wild would seem, at least to me, play more than a small role. JMO.
I see a lot of posts about squirrels not eating their HHB. The simple answer is they should not be given that option. They absolutely WILL eat the HHB (or other block) if they have no other options. It's like expecting a dog that is fed a gluten of table scraps to eat their Iams (or whatever)... if they are fed tables scraps... meats, bones, whatever.. more than enough to satisfy their appetite, they are not going to eat the "dog food". Same thing with toddlers... a kid that is raised on veggies will love their veggies (for the most part). Kids that live on fast food will refuse to eat veggies... I know I may be over generalizing, but hopefully I am making the point.
I find feeding squirrels heir block ahead of the rest of their food... handing it out individually... they seem to receive it better. It part it is just training... eat the block, I will provide you a buffet of veggies and fruit.
If a child learns they get desert regardless of eating dinner, they'll soon stop eating dinner. However, if they only get desert after eating dinner... well different results. Ditto the dog that might get a bite here or there of scraps... no dinner, no scraps.
I have had the experience of having to "train" wild squirrels to eat block. It takes months in my experience. Admittedly I have never had to convert a wild like McCarthy's beach squirrels that I think largely eat "table scraps" (analogy). I don't think, for the most part, we should expect wilds to eat Henry's block if they have a choice between that and peanuts. Or avocado. Or potato chips (in some cases). Or.. or.. or.
But I have had taken in wild squirrels that could never be released (blinded for example). I guarantee you no squirrel will starve themselves to death with perfectly fit block available to eat. I also guarantee you a squirrel given their favorite foods as option over block (and not as a reward for eating block) will not eat the block. It is largely a battle of wills and yours must be stronger. JMO.
The Henry's has all the nutritionally required Vitamin D to help with the calcium absorption. Sunlight is great (as long as they can escape to share, have plenty of water... basically prevent sun stroke) and encouraged, provides another source of vitamin D as well as generally a good thing for every animal's spirits and well being.
