Not an Emergency - X-Rays from hen with ovarian cancer

[plutofreek]

So, yesterday and today I found two dead hens. Both golden comets. Both same age. A little over 2 years. I've lost several this year. I have one that I am trying to get on her feet. She was showing symptoms of being egg bound. No egg. Belly bloated bad and somewhat firm. She was lethargic and not eating or drinking well. I have had her isolated for a little over a week. She may have this. Sounds very similar. I sent one hen off for a necropsy and the second will be brought in tomorrow. There were no symptoms for these girls. The other that passed I noticed something wrong, brought them in and dead hours later. Thank you for sharing this information. I have about 20 golden comets and several chicks that are mixed with them. I hope they all don't have the same early fate.

I'm so sorry about Kua. We had our beloved Reba put to sleep after her diagnosis. We have lost two of our pet chickens to what the vet said was reproductive cancer, and a third was recently diagnosed. Two were Cherry Eggers and the other was a California White. Our hens are about 3 years old. The vet tells us it is common in birds after they stop laying eggs. Thanks for sharing your story.

We just had our Golden Laced Wyandotte, Adzuki, diagnosed with a very large ovarian tumor same here to not knowing about this with the high producing breeds until now. We decided against doing hormone therapy and I have been researching into natural remedies. I have been giving her a morning treat of flax seed meal mixed with a little turmeric, ginger, and water every day. I've heard Ginko Biloba and Green Tea and CBD oil are also very helpful and effective, I may try adding these in to her ration as well. And might add green tea to one of their waterers! Spoiled girls, but I love them so. and want to keep our little Adzuki as comfortable as possible for as long as possible.
I'm so sorry for your Kua girl. RIP.

My sweet hen, Kua, passed away this July from Ovarian Cancer. She was a "Golden Comet" which is a fancy term for a sex-linked production hen (I didn't know this when I got her, I had only read that they made sweet pet hens). Though I never use supplemental light for my birds in winter, she didn't slow down on her laying duties, even once, since the time she came into lay. She laid large eggs almost every day of her life after she matured. She only molted once, even though she was more than three years old.
In late May, I noticed she had stopped laying. I was desperately hoping that she was just coming into molt, but I have learned enough about production hens to be suspicious. In July I noticed a small mass in her abdomen (I was checking her daily). I made a vet appointment, hoping to catch any problems early and maybe even use a hormonal implant. By the time her appointment rolled around a week later, the mass in her abdomen was huge and she was markedly less spunky.

My vet took x-rays so we could try to determine the nature of her problem, though we were both pretty sure it was reproductive, given her age, breed, and symptoms.




Please ignore the vertical bands on the image; those are from the flicker rate of the light being picked up by my camera. They are not present on the actual x-rays.

Of special note are how "bright white" some of her bones look on the x-ray. This was more evident in person.. these photos were not the best. I took these after she passed away and I was a crying mess. I digress- The bright white on her bones, most especially her long bones and spine, were of great concern to my vet (look carefully at the first x-ray, at her vertebrae especially). It is caused by bone marrow ossification which is secondary to a spike in estrogen. She usually only sees this in birds that are about to lay an egg (which my hen was not about to do) or in those that are experiencing reproductive tumors.

Also of note is how far the mass was pushing organs out of their typical locations.

For comparison.... Here is an otherwise healthy hen's x-ray (save for the piece of metal in her gizzard, which she safely digested):
This photo is NOT MINE and is used for education only. It is from the following page: http://winonafarmsinc.blogspot.com/2011/04/indesctructable-chicken.html


The x-ray couldn't give us a full picture and I still held some hope that we could do something for her. Luckily, my vet has a portable ultrasound that is somehow configured to image birds well, and we did the ultrasound. It was quite inexpensive (much less than x-rays). It told the rest of the story-- and, I may have the screen captures from this someday when the vet has time to save and send them over to me.
There was no fluid buildup, but clear non-homoginized little tumors all through her intestinal tract, and ovaries. The vet explained that even if we tried surgery, that once they are all into the intestines there is no hope of extraction. Then we slid the ultrasound wand over to look at her liver, and it was non-homogonous too. Meaning mottled; full of tumors. There was no hope. There was no fluid to drain, and no implant that could possibly reverse this much damage. It had grown very rapidly.


Here is Kua on her last day with us, at the vet's office. Notice how she looks a bit lethargic, and her posture. She was usually very alert, spunky, tail held high, and trying to eat our fingers. This is still a hard photo to look at. She was a very good hen, and a good friend.

If you view the reading below, in the first link there are photos. My hen's innards looked like Photo "B" (Primary malignant ovarian tumor in laying hen with stage IV OvCa.).

I am not as well studied in this as I am Marek's... but for those that might want to learn more, here is some additional reading I found on a few passes of google. Kua was a great hen and we miss her dearly. Her fate is one that many (some might say "the majority") of production hens meet, and it is common between the ages of 2-3 years old. It is something to consider when looking at which breeds to get, if you are not concerned about egg production and are looking for pet hens, like I was. She was an excellent egg layer, but I'd trade that to have her with us for several more years.

RIP sweet Kua. I hope this information helps someone, someday. Unfortunately, once it is at this point, there is no cure or treatment. Love your hens while they are still with you!

I’m afraid I may be experiencing something similar to you. My hen Pom Pom is almost 3 years old. She was also an egg a day layer for most of her life. We forced her into a molt last year by giving her an implant to stop egg production so she could have a minute to take care of herself. I noticed a stop in her egg production on February this year (2023). I just had her xrayed on Tuesday (4/11) and she’s showing a “mass effect” in her abdomen. It looks like her left ovary is quite enlarged. Her bones are also very bright on the X-ray, though she hasn’t laid and egg in at least a week or two. She will sit in a nesting box like she needs to lay but nothing is produced. Sweet girl. My vet is going to do an implant tomorrow 4/14 but I’m terrified it’s too late. She does not have much fluid in her abdomen, though they do see some free fluid, potentially yolk. The vet hopes the implant will shrink the mass and the vessels to potentially aid in an exploratory surgery.

I guess I’m writing this because it seems like Pom Pom might be on the same timeline as your sweet hen. How long after you discovered the tumor did your little one live? How quickly did she go from being fine and acting normal to it being too late? Should I attempt surgery to see if we can remove the tumor? I heard the surgery is risky. I don’t want to take what life she has left and end it, but I want to give her as much life as I can and I feel like time is of the essence and the longer I wait to do the surgery, the worse her odds of survival are.

I would appreciate your input. I’m so sorry for your loss. I really hope we don’t share your same fate.
