Black skin around vent? What illness could this be?

[chickenlady]

My little white turken/EE mix girl has not been feeling well this week. She is all hunched over and stays by herself.
She is roughly 4-5 years old, never had any illnesses.
She eats game bird breeder and oyster shell free choice.
Poop is starting to stick to her back side and underside now. Real thick crusty white and black poop.
I noticed twice now in the past week she layed a shell less egg from the roost at night.
Today I noticed all the skin around her vent is black. Her skin is usually pinkish.
I am going to bring her inside tonight and give her a warm bath tomorrow. I was going to treat her for cocci to start but now I'm not sure. She was wormed with eprinex a little over a month ago.
Any idea what this could be? The black skin is throwing me off. Thanks for any insight.

check for eggbound.

 

[chickenlady]

Thanks NZ. I am not too positive how to check for eggbound but under her vent feels very hard and is a little extended. Is that where the egg would be sitting if it were stuck? Could she be eggbound and still lay shell-less eggs?

 

[nzpouter]

sounds like it, egg bound in the worst will block everything, nothing comes out. Put some oil up the bum (very carefully not to break the egg that syuck in there) and wrap her up in warm towel to relax the muscles.

Thats just it, she is pooping and laying shell-less eggs. If that can all still come out, could she still be eggbound?

 

[nzpouter]

not likely then... I'm just wondering what's the hard thing in her vent could be... the only thing comes to mind is egg or tumor.

 

[nzpouter]

actually it could also be a bruise from mechanical injury.

 

[chickenlady]

Not sure. The area just below the vent is hard and protruding slightly and around the vent hole the skin is all black. She still looks in great shape. Her comb is bright red. She holds her tail up like normal. She just sits with her neck scrunched down into her shoulders and sits in one place. I have seen her eating and drinking and yesterday she went out and freeranged with everyone. She has me stumped. She will get a good bath tomorrow and I am giving her vitamin water.


ETA: What is mechanical injury?

slam/ hit against something.
