The high dose of Calcium Citrate + D3 is just a short term thing to see if things improve or not. (see if things reset) You do not want to run her on a high dose long term as that can have serious long term and permanent side effects, actually making things worse. (too much calcium is bad)
If...
Give her the Calcium Citrate + D3 daily for a week. If you see improvement, then try a D3 water supplement to see if you can maintain the improved egg quality with the free choice calcium options.
If you don’t see improvement, it could definitely be an issue with the shell gland as mentioned...
