Is this her tail necrotic or is this some kind of growth or something

[aart]

Her abdomen is distended

Does it feel squishy like a water balloon or a hard lump?

She is eating and drinking. I gave her some cottage cheese with crushed oyster shell in it because initially I thought it was egg bound. Her abdomen is distended and she is sitting up tall like an owl and trying to contract something out at times. She ate that very quickly and wanted more. She is pooping also. I used permethrin dust around her vent also. Keeping her in a laundry basket in the house tonight.

Sounds like she could be egg bound.

Since she has not been laying, her posture might be related to a reproductive disorder such as salpingitis, internal laying, egg peritonitis or others. Some hens will sit or stand more upright with internal laying. In the morning, you might want to insert a lubricated finger inside the vent about 1-2 inches, and feel for anything obstructing the opening, such as an egg or lash egg material. She may not need to be away from the flock if she does okay during the night. I would use your own judgement there, and see how they treat her if you place her in the coop. Here is some reading:

Where are you located? Has it been very cold yet? Hopefully, this is just a little build up of crud back there, and she will be fine in a few days. Sometimes they can get pecked around the vent, and some hens can have vent gleet, a fungal infection. Glad that it wasn’t a prolapse. Let us know later if she is eating and drinking.

We are in Ohio. It’s not too cold yet. She is eating and drinking.

This is exactly how she is sitting. I can check tomorrow. I’ll read the article tonight. Thanks. She is sleeping now in the laundry basket. The other hens weren’t bothering her today.

Water balloon

I’ll be the gross one and suggest the smell test - necrosis is very stinky and unmistakable.

Water balloon

Ascites.

Looks like lice eggs to me. I'm not seeing anything necrotic.
