This person told me that he had not gotten any eggs from her the previous year, but was willing to give her to me and see if I can get her to lay eggs. I found out that she was eating her eggs, hence the reason my friend thought she wasn't laying, she would lay her egg and immediately turn around and eat it. I decided to put some eggs in a feed dish and watch her to see if I can determine what she's actually after as I was starting to think she was after the shell and not the yolks. I put 3 whole (in the shell) eggs into her feed dish and stood there and watched her. She promptly broke an egg and instead of going for the yolk like they normally do she ate the shell, as soon as she was done with the first egg she broke the second one and ate that shell also, she ate all the shells and left the yolks. It seemed like a light went on in my brain. We have as a rule always fed our egg shells back to our hens, dried and toasted/roasted. We immediately gave her a cup of dried crushed egg shells. In three days she ate one whole cup of the dried egg shell. We kept the shells available to her as free choice. I cannot guarantee this method to be fool proof, it just worked for me.
3 days after we fed her the dried toasted shells she quit eating her own eggs, she then proceeded to lay 12 eggs, became broody and hatched all 12.
I tried a lot of other supposably fool proof methods that people told me about, but for this hen none of those worked.
