Gut lining will be heavy and stringy, such as you suggested in your analogy, however it is generally pink in color. Heavy red, deep red, clotting, would be more concerning.
You could put them all on medicated chick feed, which is Amprolium, to head off a bout of Coccidiosis, if everyone seems generally well and there are no other messy poos.
It won't hurt them, will be a mild treatment, and can prevent a Coccidiosis crisis without having to resort to heavier meds.
It will not treat a true outbreak, however. For that you will need to give either Sulmet or Corid.
You can still eat the eggs while they are on the medicated chick feed. The Amprolium level is so low that it does not present in the eggs to any significant level.
I would leave them on it for several weeks. The Amprolium literally starves the coccidia protozoa by not allowing them to metabolize vitamin B. The level is low so that the bird still builds up an natural immunity to the coccidia, but at levels that are low enough so that it doesn't overwhelm the system.
Otherwise, just watch and wait. Adding ACV to the water, raw with mother plastic container only, and some probiotics through yogurt or keifer can also go a long way to balance the gut and help prevent any overgrowth.
