These are a mini rex over NZW. The mini rex is a little more aggressive breeding and I was having some trouble getting her to breed, so I stuck her in with him to see if he'd get the job done and he did - we have nine in the nest box. They'll probably all be meat.
I found this page with a nearly identical situation but no chilled kit. But the post blockage swelling and redness and the almost gaping wound look to it is the same;

It turned out OK for them with just some daily cleaning for 5 days. Hoping for the same results.
Maybe missing one stimulation just cascaded it. Assuming it popped out of the box while nursing. If mom has the rest of them eliminating properly it was probably just a fluke
