Pullet with poopy butt and....

[aart]

Did you get it down her @MarkJr ?
I'm not one to pill a bird either, I mix whatever up with crumble and they chow it down.
Am also not one to 'medicate' quickly.

Since she free ranges, who know what she might have eaten to upset her system.
I'd get her on nothing but a good chicken ration and plain water for a few days and see what shows up.

When I have a bird that is acting 'off' I isolate bird in a wire cage within the coop for a day or two....so I can closely monitor their intake of food and water, crop function(checking at night and in morning before providing more feed), and their poops. Feel their abdomen, from below vent to between legs, for squishy or hard swelling. Check for external parasites or any other abnormalities.

Best to put crate right in coop or run so bird is still 'with' the flock.
I like to use a fold-able wire dog crate (24"L x 18"W x 21"H) with smaller mesh(1x2) on bottom of crate under tray.
Then you can put tray underneath crate to better observe droppings without it being stepped in. If smaller mesh is carefully installed, tray can still be used inside crate.

Glad you got it down her, but I'd still isolate to monitor her digestive system(as I described) for a few days.

Will do. She layed this morning. Dark brown perfect egg.

Also add she does come off roost and outside with everyone first thing in the morning. She eats scratch, bellies up to the crumble pile, then goes off to the side and sets.

Right back to where she started after I rudely rousted her for pictures.

Literally the only outward thing that’s ‘wrong’ with her is the poopy feathers, and she’s lethargic.

I have a chicken that this happens to. She just has more fluff on her butt than her sisters do. I clean her about once a week or so. I'm not sure about the lethargy though.

 

[MarkJr]

I cleaned her up. Gave her a trim.
She’s been lethargic for about a week. Beats everyone into coop by an hour or more. Lays around most of the day. Doesn’t come for scratch. She did eat about a tablespoon of scratch after I finished ruffling her feathers, and immediately went back into the coop.

Is she possibly going broody?

@MarkJr, is she a Black Australorp? She's very pretty and, other than the diarrhea looks to be in good health. Her comb color looks good to me and her feathers look thrifty. Let's see what our experts think.
