I'm not the only one who has observed the erosion of the hatchery DP over the last 4 decades and consequences of pushing these birds to higher and higher lay rates and at what cost? SpeckledHen, long term backyarder, far longer than most, long time moderator here, (tough job) and one of the most common sense, wise folks I know recently posted the following in a reply. I've seen SpeckledHen (Cynthia) post this basic insight dozens of times over the past few years. I recognize experience when I see it.

What you are seeing is not really egg binding. The age and the fact that you have hatchery stock from one of the big production hatcheries tells me that they are starting to die from what may start as salpingitis infections/egg yolk peritonitis and end up with internal laying. All of those are sort of interrelated. I lost almost every original hatchery hen I had (from another big hatchery) to internal laying/egg yolk peritonitis. It's very common in hatchery hens, especially the breeds that are the most popular with feed store shipments like the Rocks, Wyandottes, Orpingtons, Reds, etc., but can be seen in other breeds of low quality genetics.
We've necropsied many of them, seen the terrible cheesy gunk clogging the oviducts (like what your hen passed) and in the abdomen as well. That is solidified infection and egg material combined. It's genetic/hormone based-no prevention, no cure. You have to start with better quality stock. My hens who are not direct hatchery girls do much better-I have 6 year old hens out of hatchery parents who are still laying and seem well other than arthritis. The further from the hatchery generation you get, the less you'll see that stuff. Been battling this stuff for years and there is truly no way to beat it other than get birds made of better genetic stuff.
All the calcium in the world will not fix internal laying. That is not the cause. There was a study that seemed to say that flax seed given regularly might help offset some of this, but mine did have that occasionally and it didn't seem to have an effect. Could be it should be given from a very young age, very regularly, but this being genetic/hormonal, not sure how much good it would do.
