Do this experiment: put a fresh good egg with a hard shell in a glass of vinegar and watch what happpens to it overnight. Feel it with your finger.
Whatever benefits ACV may or may not provide to the overall health of a chicken, the bottom line is that it leaches the calcium out bones and egg shells. So if your hen is giving you soft shelled eggs and you are giving her vinegar in any form for any reason, stop it immediately.
Also if you are not currently providing her with oyster shell in a separate dish available 24/7, please begin to do so immediately. Grit is necessary for digestion, but it does not provide calcium which is necessary for the formation of good hard shells.
Good luck and please keep us posted!
