Chicken with stuck grass poop?

[Tervish]

My favorite chicken (of course!) 6 weeks old, has poop stuck hanging out of her vent. It is full of grass strings! The chicks have been out in a grassy run area for about 3 weeks now so the grass exposure is not new. I tried to pull very gently on it but no movement. She is trying to pull on it too. I am thinking of trying a butt bath but am welcome to any ideas or tips here.

They seem to lack grit for proper digestion.

If she is bothered by the grass not coming out, just carefully clip it.

They have free choice grit, and I have seen them all get into it.

I did trim the grass strings a bit, and used some water to thin it out, and she has passed it now. And her body shape is back to normal...she had her tail held very high and her whole outline was different.

I was concerned when I saw her passing feces *around* the grass plug but I think it is okay now. I'll keep an eye on her.
