My girls are new layers and I've gotten a couple of soft shelled eggs. This latest held together when i picked it up and it was in the nest box not on the floor. Anyhow I'm going to get some oyster shells but they are expensive. Do I have to give them to the girls on a regular basis? Can I just give them some to get things going? Maybe I can get the doc to prescribe Boniva? Think Sally Fields would know if it will work? Just answer the serious questions if you'd like cause I am serious.
