Ok everyone - big update. We went to the vet today and Nani supposedly has Egg Yolk Peritonitis. They did a fecal test and nothing looked abnormal (though she's been taking antibiotics so maybe this wasn't even worth doing), and then we did an ultrasound of her abdomen and he saw what looked like 'an' eggyolk. He pierced through her abdomen and got a sample of the liquid in there, which was egg yolk. He said it looked clean but didn't know if it had bacteria or not, and I've been giving her an antibiotic for the past 5 days. (In retrospect I wished we would have had tested it for bacteria and I wished he would have completely drained it). He also did mention that it is not for certain that he didn't pierce actually through a soft egg shell while doing this. I haven't mentioned this in the posts, but I have been unaware of Nani's laying status as the hens I've raised have graduated from their coop pretty much altogether at this point and I have no idea where they lay their eggs any more and I've mainly lost interest in having eggs as a part of my diet anyways. She was a regular layer and then I believe her production dropped off a bit and then I lost track as she's a free bird. In retrospect, some of the eggs from either Nani or her sister (another RIR same age) were either slightly deformed, and/or had little calcium (?) buildups on the outside of the egg, creating a very rough texture. Some times these deformed eggs have been very hard / thick shelled, and I've also seen some super soft shelled ones and I always suspected they were from Nani. The thick shelled ones with the rough texture I remember being a pale pink, different from her normal deeper pink / brown color. (I'm just now editing and adding in this info as I see a connection here to all of this.. curious if it's IB, which I never spoke about with the vet) I forgot to tell my vet all of this! Though I have been unaware of her laying status, it seemed pretty obvious to both of us that she hasn't been laying for a while now due to her weight (at least 2-3 weeks) so it's hard to say whether she'll continue to internally lay, if that is what she in fact doing.

He said initially he believed whatever was going on with her was serious as her weight has gotten so low and she virtually has very little muscle tissue, but he wasn't convinced it was a reproductive issue as she seemed somewhat normal / not entirely swollen in the back. He confirmed she is not dehydrated, and does have clear, alert eyes. Now with an EYP diagnosis, all the yellow coloring in her poo seems to make sense (though at times it could have been the dye in her antibiotic pills), and maybe the 'fleshy bits' were cecal core from her bout with coccidiosis (If it ever really was coccidiosis! I wonder if the blood in her poo could have just been somehow apart of what's going on the the EYP?)

Also, some of her liquidy poo consistencies have been like egg white and now that would make sense I believe. He told me he honestly has little experience in familiarity / treating EYP. I googled and read about sterile vs unsterile EYP and asked him if he could drain the rest of the egg yolk from her abdomen in a sterile way and he said that doing that is not a sterile procedure, so somehow I let that slide though I now regret that, as he apparently had already done it anyways. I was still curious if her having an impacted crop is related to the EYP and he said it could potentially be fluids backed up, though her crop is fairly small and it doesn't feel like any firm object is in there. He eventually put some tube down her throat to draw in some liquid, but he said literally nothing came up, so somehow her crop is actually empty though it doesn't feel like it is? He said maybe it's because the crop tissue is all compacted or something? Seems odd to me but if that's really the case, than Why is she not eating much? Just general not feeling well because of the EYP? How can I make sense of her involuntary 'twitch' when she goes to drink water?

I decided to give her some more time, as she doesn't seem she is in pain or miserable at this point from what I can tell, and there is still a will to live. She still wants to eat papaya and spinach. I've taken her out to range with her sisters a bit each day and she really enjoys it and is actually digging and looking around, but is only 'eating' tiny particles of sand and such that makes me think she's either trying to just go through the motions because that's what she does as a chicken - although she doesn't actually have interest in eating anything. And/or, maybe she's looking for specific things to help break things up for digestion? I put some grit in front of her but she had zero interest in it.

The doctor gave me more antibiotics and an anti-inflammatory for her. I in the mean-time will be doing as much research about EYP as I can and will do my best to support her in case she can somehow possibly clear it, and if she doesn't show improvement and seems to be suffering I will go another route.

In the meantime, if anyone has any thoughts, questions or information / good resources on any of these topics and specifically EYP, please send them my way!

Thank you so much and have a beautiful night / say wherever you are! <3

Curious where you heard that you shouldn't have vitamin c with oxytetracycline? I mentioned this to my vet and they actually said it should be ok, and honestly to encourage Nani to eat whatever she's willing to eat at this point.

Glad you were able to see the vet.
Not sure where you got the idea that I told you not to use Vitamin C unless you are confusing it with Calcium. 2 totally different things. You kept mentioning Vitamin C, so I brought it up again in another post ??!
Your vet has a drug manual where he can look up all contraindications - so I'm glad he was able to hopefully clarify that for you.

There is plenty of information here on BYC and on Google about internal laying/reproductive disorders , just do some searching.

I hope all goes well for you and your hen. Good Luck.


The Oxytetracycline may help with inflammation and infection enough for you to be able to start getting the crop to clear. Eliminate any dairy or extra calcium (spinach included) while she is on the antibiotic. I believe it's one that calcium binds with and makes it less effective.

Thank you for the nutritional tips, especially about not to use the spinach with the Oxytetracycline.

I'm trying to figure out what I can feed her to nourish her that doesn't have vitamin c, dairy etc. while she's taking Oxytetracycline antibiotic.. any thoughts?

I've been trying to keep her on a liquid diet though it was hard to keep it liquid without vitamin c,
Not sure about Vitamin C? I only mentioned not using foods/products that contain calcium when giving the Oxy.
Papaya is an excellent source of vitamin C

Hey guys - I’m still confused with how her unusual crop situation fits in with her EYP diagnosis.

Tonight I was giving her her medications orally via syringe, and the same thing happened as a couple nights ago (though worse this time) - she kept putting her head back and continually attempting to swallow after I had given her a couple syringes of liquid.. I thought it was enough time between, but maybe it wasn’t. I was nervous last time that I got fluid into her lungs but upon reading the symptoms of that it didn’t seem to be the case. Tonight however when it happened there was also some audible breath / gasping and when I massaged her crop that felt enlarged, it deflated and she burped.. seems like air was trapped in there? (How does that correlate with having just drank liquid?) And then when she sat back down her crop filled right back up, I massaged and again it deflated. What is going on? I wonder if this could indicate something is going on lower in her digestive track than her crop? I opened her mouth and didn’t see anything, but I noticed her nostrils looked a little bit wet and see formed a water droplet on her beak twice. She also seemed to have saliva on the inside of her beak in the beginning of when it happened, a couple saliva strings connecting the top part of the beak to the lower part when her mouth was open and tilting her head back.

I want to figure out somehow if she’s having a digestive issue or something separate from or connected to her EYP.

I read somewhere when birds have air-filled crops that they think they are full - maybe that’s why she hasn’t been eating? Does she have crazy gas from something and that’s been why her crop hasn’t felt empty and when the vet tried to pull fluid out of it there was nothing there? I wish to figure out all of these answers...

EYP affects everything. The way I think about it is that she’s septic. The infection can cause inflammation of just about everything. It throws their entire system off.
 
You could try including some digestive enzymes in her food. Make sure they contain cellulase as any blockage is likely to be plant-based. Mix capsule contents with whatever she will eat - yoghurt or papaya fine. Might help with her crop issues?

Thank you, I was just asking about that in a different post! Do you have one that you recommend? Is digestive enzymes for humans acceptable for her?
 
Aloha everyone! I will no longer be posting in this thread unless anyone else has anything to add here, and in case anyone wants to follow along with Nani's journey - the newest post is now here:

Thank you all so much for your experiences, information, suggestions, best guesses, and overall support. I am so thankful for this community, and as I learn more I will most definitely do my best to help others as well! Take care everyone, all the best to you and your chickens <3
