Yellow/Green poop, dirty butt, lethargic, breathing sounds like rattling

[Brownix Hobby Farm]

My entire flock was given a dewormer and VetRX, tonight. I put a probiotic, and a flock wellness solution (vitamins, mineral, oregano oil, and other wellness ingredients) in the their water.
The sickly hen is still in bad shape. Not eating or drinking much, but some. Still watery yellow urates.

I would offer a little mushy wet chicken flock raiser, and a bit of scrambled egg or tuna a couple of times a day. Adding water to everything will get more liquids into her. She probably is missing her flock, so I would give her some supervised visiting time with them.

I can confirm no egg has been laid since she has been in quarantine. That was Sunday, so we're on day 5. She is eating and drinking very little. When I gave her time with the rest of the flock, she was pecking at the ground, and eating just a few mealworms. She is still coughing and rattling breathing. I have used VetRX on her daily and soaked her in warm Epsom salts twice now.
