It would be useful to have a gallery of pictures of poop along with a comment on the health of the hen so that those of us who are fascinated by this subject can see what is normal and what is not. These are pictures from healthy hens (as far as I know) This is normal. I think that this is a cecal poop but a bit darker than normal. Our earth is black here so they may have been eating that. The hen that did this has probably been stealing the cat's food. It seems to make it watery.
