My question is how to avoid this state? I am apprehensive that I may be overconsuming calcium in the form of two eggshells per day. What is the best dose per day for the athletic young man and what are the best arguments pro and con?
Firstly, if you eat calcium rich dairy products such as cheese or milk then I doubt you need any extra calcium.
So how much calcium is in an eggshell? I shall assume you are talking about averaged sized chicken eggs.
Most of the estimates seem to say that a chicken eggshell weighes apporimately 5-6 grams. About 95% of this is calcium carbonate. With around 2 grams of elemental calcium. (Source)
Each egg shell probably contains several grams of calcium carbonate. Upto 6,000 milligrams.
If you eat 2 eggs shells per day you could be consuming many times more calcium than you need. I would be cautious about overdosing on it.
I don't know of any recommendations for how much eggshell to ingest as a calcium supplemnt. Maybe you could grind it into a powder and add a pinch of it to you food each day. Or a quarter teaspoon of ground eggshell. The calcium from eggshells appears to be easily absorbed by your body.
I would suggest that you stop eating 2 whole egg shells a day.

Some scientific links to pubmed:
The present study indicates that healthy late post-menopausal women with an adequate Ca intake at baseline may increase BMD of the hip within 12 months following supplementation with the chicken eggshell powder-enriched supplement.
The bioavailability of calcium from this source, as tested in piglets, was similar or better than that of food grade purified calcium carbonate. Clinical and experimental studies showed that eggshell powder has positive effects on bone and cartilage and that it is suitable in the prevention and treatment of osteoporosis.
You're not going to develop fibrodysplasia ossificans progressiva from eating too much calcium. If that's not what you mean by "ossified" i have no idea what to say.
You can also roast eggshells over an open fire for 30 minutes. I've never tried it, and I really don't know why you'd want to do that, but you can indeed do it.
If it's strong bones you are interested in for climbing the mountainous ridges were you are camping out in the wilderness, well, then my advice is to up your intake of eggshells for sure. The calcium is more bioavailable than that of whole milk cheese, which I know you also gorge on.
May the Paleo force be with you PersonMan.
Oddly enough I have bones in my scalpula that never fully ossified and yet I got a calcium deposit in my patelar tendon seemingly from consuming extra calcium while I had tendonitis.
I don't go out of my way to get extra calcium anymore. I just focus on my vitamins and other minerals and hope it's enough. Actually, I got hit by a car recently and had some bone bruising but no break so I guess I am doing it right.
I believe that vitamin D plays a big role in how calcium is metabolized so you might want to look into that as well. If you had a lot of spare calcium kicking around in your bloodstream, isn't it possible that could contribute to plaque formation in your arteries?
