Lethargic hen, yellowish poop, dirty rear

[NightingaleJen]

Our seven month old EE was lethargic with tan colored poop on her rear this morning. I carefully cleaned her up, then put her into isolation with feed, water, nutriDrench water, and a little hard-boiled egg. She nibbled at her feed but that is it. Hasn't laid since Saturday or yesterday. Is it a broken egg inside? Would a warm bath help?

The flock has not been wormed.

Well, I gave her the "Spa Treatment" via another thread on a similar topic—a warm-water epsom salts bath, a little olive oil (that was tough to do, so I got her to take as much as I could; will try more with some hard-boiled egg in a little bit), and back to her isolation ward. I put the heat plate in the ward just in case it helps her. I'm not sure. :/ She did seem to enjoy the bath and even preened a wee bit.

At last check Matilda had laid an egg. It has odd yellowish streaks on it. However, she still seems lethargic. I offered the egg with oil but she just went back to the corner. She does have plain fresh water.

Anyone have any thoughts or suggestions?
