Hello again Isaac!
So I was not able to get a picture of her vent. She bit me really hard after I administered her penicillin and I spent 20 minutes trying to catch her and was unsuccessful. I did however get these pictures to try and add onto this. When I opened the coop this morning I did catch her to administer her shot. I put her in a cage while I drew up the fluid and pulled her out when I gave her the shot. ( this is when she bit and got out of my arms ) as you can see, her poop is very watery and white. In the other picture it shows how fluffed up she is. She is also shaking her head ALOT. almost constantly. I treated the whole flock for mites and Worms as a precaution a week ago. So I don’t think it’s mites Or worms why she is shaking her head. It’s got to be something else. Could this be infection? Cocci? Neurological? Thank you in advance!
I see she's outside. It may be better if you take her inside, and set her in a calm, quiet area with feed and water provided. To aid in expelling the material you could set her in a bathroom, and turn the shower, not touching her, but to raise the humidity in the room.
Hopefully, she passes the rest of the material soon, due to the slimy-like nature of the material, it's often hard for them to properly expel the material which can result in some lethargic behavior. If she doesn't pass it soon, I may try to lube up my finger, and insert it into her vent and see if I can feel any egg material, and try to gently pull it out.
The head shaking could be due to mites, ear infection, neurological, if she's gasping afterwards it could crop-related, or some sort of blockage. A video would be helpful. What did you use for the mite treatment?
I would check her crop, her abdominal area for swelling, and her whole body for mites if you can. If she is on the older side, and the lethargy doesn't improve, and the yellow-colored urates persists, it possible she has a reproductive disorder.
I will tag
@Eggcessive , and
@Wyorp Rock , as I hang out more on the duck forums, and am a little more familiar with the protocol we do there. They may suggest something different along the lines of treatment.
