I have my new baby in a cement mixing box. She has a small dent on the back row of her shell. I don’t keep a cover over her enclosure. I feed organic spring salad twice daily. I put some vitamin food in it. Is that ok?The rate of pyramiding doesn't appear to have changed much. 60-80% humidity is too low. It should be 80-100%, in a closed chamber, with low wattage basking bulbs set at the right height for the correct temperature under them. Humidity should be 100% all the time in your humid hide. The goal is to simulate monsoon conditions. Imagine heavy rains when its 100 degrees every day. Think South Florida or New Orleans in July. That is what we are trying to simulate in the middle of your Nebraskan winter. There is really no way to do it without a closed chamber.
Stopping pyramiding in progress is much harder than preventing it in the first place.
Soaks should be at least 30-40 minutes and longer is fine too. This also helps stop the pyramiding.
Babies can't eat hay, and all that hay in your damp substrate is going to mold. Save the hay for when your baby gets up to about 12".
Coco coir is not my first choice for sulcatas because of the mess. It will be less messy if you hand pack it down.
