A problem of a special kind, chickens die eaten from behind "sewer". The cause is not predators. Here is the story...

Hello dear friends,

The story,

Approx. 25 chicks hatched about 7 months ago, they initially had difficulties in thriving. However, we managed to solve this problem with your help in the forum here. The problem was with the feed, possibly also a kind of coccidial infestation.

Now these chickens have developed splendidly afterwards. They reached an average weight of approx. 2.5 kg and started laying eggs at approx. 5.5 months. Everything went so far wonderfully. Vaccinations are not available here in Gaza, only in limited numbers and limited varieties where I can not get, so my chickens were vaccinated against nothing, as this bothers and sadens me. Nevertheless, the chickens grew quite well in isolation from the outside world without being infected.

Current problem:

About 28 days ago I got a new rooster as a foreign blood enrichment "NN in black in the picture". Just a rooster. After about 20 days I found a hen dead on the floor. The hen's intestines were eaten from behind. I thought this would be an isolated case. I didn't know what it could be. One thing is certain, no predators come here, not even a mouse comes in. After 3 days I found the second hen the same thing, then the third hen, whereby I could accidentally watch the third case what happened. She suddenly appeared apathetic and looked for a corner she seemed irritated she wanted to shit or lay an egg. Normally when laying eggs she rises in the nest, now she was on the ground. A yellow puree came out but also part of the intestines. When the intestines pulled out a little, they were picked by the rest of the chickens and taken out. I could get the 4th hen out and isolate it immediately after it was picked. She was given sulfamethoxazole trimethoprim for 3 days and showed no symptoms, everything seems to be normal. I brought her back to the hens, in the evening I found her bleeding and the intestines are behind.

The 5th hen has been apatic since yesterday and is now in quarantine. She now receives metronidazole and sulfamethoxazole/trimethoprim but also 100 mg ciprofloxacin 2 per day. Yesterday as i brought her, she shit the yellow puree as seen in the picture below, and she also has a green diarrhea. Today she is a little more active and alert. I suspect the yellow puree is an egg yolk.

Since it seems a series of death, I would like to ask for your expertise and advice. If we can diagnose the pathogen, then I can reduce the medication to at least one or I know how to save the rest of the chickens.

My guesses.

A pathogen slipped through the rooster, which attacks the egg apparatus. Which leads to inflammation and irritation. Since I have only observed this happening in the laying hens and not in the younger ones. This affects the hen which the Rooster climbs.

Which pathogens are behind this special kind of death?

Hmmm. It might be vent prolapse. What do the intestines look like? (no pictures please). If the intestines look like a big red blob it might be vent prolapse. I can’t think of a disease that would disconnect the intestines from the insides.

Then, What is the cause of the yellow puree in each case?
 
I did not find any typical swelling in the rear of the hens. This would be typical of vent prolapse . Secondly, this phenomenon will not affect all hens one after the other. And does not explain the cases described above. It's puzzling, don't you think?
 
I would have to say some type of infection that Neon Green Poop is not right at all nor the yellow poop.

If you could get some testing, it would be good. I know that's likely not possible.

I'm no vet or expert, but Green poop like that makes me think Enteritis. Yellow poop like that - maybe E. Coli, Histomaniasis maybe?
Some type of infection to the intestines either way, especially if the intestines are coming out when they poop. Likely you have more than one thing going on.
Any way possible you can get a local vet to run some fecal floats and gram stain tests?
 
The liver was clean for histomoniasis. Does e-coli make the whole clinical picture as described above?, I am surprised that this only affects laying hens. There are other chickens, roosters and not ready to lay hens that live with and are healthy.

Samples Testing needs experienced staff. This is not the case here.
