Hello,

I have done a bunch of reading, but was hoping for some more specific advice since these 2 things seems related.

1 - We have 10 laying birds that are all 1.5 years old. The lady with a swollen abdomen is definitely the top of the pecking order, but very sweet. She is a Buff Orpington. She has always been the largest bird in the flock (we have other Buff Orpingtons, but also Silkies and Black Australorps).

2 - She seems to be moving normal, is chatty during the day, and all other behaviors seem to be normal for her. She is very social and always approaches us when we go up to the coop.

However, we noticed a couple weeks ago that she was going to sleep in the poop box instead of getting on her normal roosting spot. This was not abnormal, as she usually likes to scrape around in the poop box before she later climbs up. Our poop box is large, filled with Sweet PDZ, and is cleaned at least once a week.

Around the same time, we started seeing soft-shelled eggs from her. This was slightly odd because she loves snacking on the Oyster Shells and often has Calcium deposits on her eggs. She has been laying almost daily for 2 weeks now. Some of the eggs still look like her typical ones, but many are soft-shelled.

In addition, I happened to be cleaning her off yesterday and she felt a little bloated. To make sure, I compared her with the other large birds and there is definitely swelling. I have not seen her poop recently, but that does not mean it is not happening.

Again, all other behaviors of hers are completely normal.

The only other factors I can think:
We recently added 10, 6 week old chickens to the run (separated and in a different coop).
We have had a lot of rain recently (multiple days in a row) and they were spending more time indoors.
No other chickens are showing any of these traits.

3- All birds in the older flock have been fed the same feed from a local mill since we've had them (besides switching from starter to layer).

We give them mealworms a couple times a week, food scraps like lettuce and other veggies, and spent grains (when available) from a local brewery. We also let them go out in a mobile run where they can peck at things in the grass or our leaf compost pile. Their water is always fresh and is mixed with Rooster Booster electrolytes/probiotics.

We have given her some nutri-drench a couple times in case she is low on nutrients. We have also rubbed some VetRx around her head/wings as a just-in-case, but have not noticed any breathing issues.

4 - Their coop (in addition to the poop boxes already mentioned) is spacious and has pine shaving bedding which stays very clean. There are several nesting boxes, which the birds have always rotated through (especially since our silkies get broody). We use sand in the run and this has worked well the entire time we've had chickens.

5 - We would like to treat ourselves, if possible. If not possible, we do not plan to take to a vet, but would like her to be as comfortable as possible.

I will try to take and post a couple pictures once I get home tonight.
 
Terrific job of describing the issues! Excellent information.

I believe your BO is showing early signs of oviduct inflammation due to a calcium deficiency causing shell problems. By soft shell I take it to mean "rubber" or shell-less eggs, not thin-shell eggs. Correct me if I'm making an incorrect assumption.

A shell-less egg is very uncomfortable to try to get out, and it can cause inflammation if it collapses, even if a hen manages to eliminate it. The inflammation can lead to infection, so I often will treat with an antibiotic if I get the feeling the hen is starting to feel sick.

In spite of a hen consuming oyster shell, their body can sometimes not assimilate it. This is why I use calcium citrate as a supplement instead of calcium carbonate, which is what oyster shell is. Calcium citrate can often be absorbed when a hen isn't absorbing the oyster shell.

I give a half a 400mg tablet once or twice a day for a small hen and a whole tablet once a day for a large one. I keep it up until the eggs are consistently hard-shell.

Hold off on using an antibiotic unless your hen is not feeling well.
 
Thank you for all of the information @azygous.

Sorry if I used the wrong term. The eggs do have shells, but they are all thin. She actually laid 2 eggs yesterday. I have not seen her do so before.

The one on top looked normal and had a thick shell. I am sure that this is true for many people with backyard chickens, but our normal eggs tend to have much thicker shells than any eggs bought from the store.

The one on the bottom had calcium deposits, but was very thin...hence the crack.

That your hen laid two eggs close together is something I've found that calcium citrate also helps correct.

Releasing two yolks in quick succession sets the hen up for a collapsed egg in the oviduct, and that may eventually lead to infection (EYP). The shell glad rarely has enough calcium reserves to lay down more than one shell at a time.

I had a young hen that began this year's egg season with this problem. It took a month of calcium to correct it, and she's laying one egg at a time now, and she's escaped infection.

All of that information is definitely reassuring and helpful as I was looking at completely other issues from what I read.

Can I find what you are talking about at TSC or should I just get it from a standard drug store?
