Since they haven't molted yet, this could be PPS. I thought attack because of the crushed limbs but I guess it's also possible he dropped them and started picking/eating at them. They definitely have plenty of space. You could ISO the crab just by dividing the tank in some way.

I would try to vary the diet more, especially protein sources. Dried crickets, mealworms, and shrimp usually go over very well and keep well too.

Upping the temp as soon as you can may increase activity. Do they mostly hang out near your heat source?

More shells never hurts.

I was able to get a lamp and get the temp to 80-85

Any suggestions on how to keep the humidity automated like on a timer
