trim up any of the feathers that are extremely poopy near the vent and pictures are needed. Has there been any change in feed/diet? Has she gone down in pecking order or become lethargic?

This morning she was in the nest box and stayed there all morning (I had to go out) until I got her out to back her. I annoyingly forgot to get a photo before I bathed her. The poop that was stuck to her looked normal, the bath water was very dirty afterward. I used epsom salts, she did drink some of the water i managed to get her clean water to drink while she was in the bath. I trimmed the feathers and I will probably put athlete foot treatment on her vent later. She is drying of now in our warmest room (our house is cold.) But she is lethargic band not drinking anymore and hasn’t eaten a thing. She also has a squishy swollen crop (sour crop?) that made a gurgling sound when I massaged it. I’m thinking she got egg bound and the egg broke inside her. Not sure how to get the rest of the egg out. Here is a photo of her poop after the bath that doesn’t look normal.
