Dixie was the smallest and last to lay but she didn't isolate. We also had 1 of the flock lay some soft shell/balloon looking eggs under the roost 5 days in a row a few months ago but that resolved and we never figured out which one was laying them.
No rats or signs of rats that we have seen. Their coop has an attached run that has a solid roof and has 1/4" hardware cloth screwed in between frames and there is also a buried perimeter skirt covered in rocks. We changed their water and made sure food was full before we left for the weekend.
Yes, the others are healthy. I suppose there's a possibility of a pecking order skirmish happening? They normally get to free range during day hours and it was the first time (since they were really young) that they were locked in for a several days straight together. I think for 6 they do have plenty of room though in our set up to discourage fighting?
