Teach, what a bittersweet story. I'm so sorry. Thanks for sharing.
Cyn, I'm not convinced it's a feed related problem, although someone had mentioned genetically altered corn. But until someone does a in depth study, I'm leaning towards genetics. According to my journal I've kept since '03, my first line I purchased and bred from, says all but 1 hen died from internal laying, starting at age 1 1/2!!!!!
From that line, I still have a hen that is 6 years old and laying occasionally. Of the roo's I kept from that line, one will turn 8 next week, other 7 years old. I do not breed from this line at all, so no offspring.
Next line I got 5 years ago and have not shown any internal laying problem and I've bred them. Their offspring girls do not show a problem so far either.
My 3rd line from another source is not showing problems. They are young but laying, so time will tell.
Total mystery to me, but I'm thinking along the lines of "Better genetics, less internal layers."
