I finally decided that I had to cull my non laying Leghorns. All I have been getting is a mess from a soft shelled egg from one of them in the nesting boxes. Since I didn't really want to do the culling myself, I placed an ad on Craigslist. The first person who called was looking for free birds to eat the bugs on her ranch. I am so glad that they will live out their life chasing bugs, instead of going into the stew pot. These were over 3 years old and had laid well for us. Now I have to decide what breeds to get next.
