Oh, I've still got some of those old pix. LOL
The laying rate DID subside. An ISA Brown is a 4 way nick. They've been researched as a cornerstone hybrid and was a pilot program bird for many of the later commercial layers. The reality is that subsequent generations laid well, but the egg size decreased a bit, as did that early point of lay and other aspects of the original ISA. It was a fun experiment, but it ran it's course.
Here's some of the White split birds from the original ISA's.
Here are a few of the "negative reverse colored" type offspring.
Now, here's something I don't know if I stressed in that old thread. EYP and ascites. These ovarian and reproductive diseases became profoundly common as we went along with the program. In fact, it was this sad fact that drove me away from high production birds altogether, for my personal flock and hobby. To be frank, it drove me back to heritage fowl. That's all I'll say about it, unless there's more to the story you care to hear.
