Unknown Disease: A Professors Story

16.04.2023
DISCLAMIER: Everything is based on my own experience, my speculations and my own research. Im not a professional. 

Poppi as I call her, but her full name is Professor Ratigan. Named after the villian from the movie "The Great Mouse Detective".

 As a pullet Poppi was full of spark and saz. She often as a chick challanged her brother in the pecking order. Just after that first egg she started changing. Her self confidence slowly went away (I didnt really notice back then since I was so new to chickens.)

Everything was normal until some month after she just started laying. It was so suttle so I did not really notice that something was wrong all the way back then. Now reflecting back I know it started way earlier than I tought it did. 
The first real symtom that was obvious, she started losing her crest, slowly. You could think that this was a molt, but first molting that young is rare and it didnt really act like a molt. What came later on is that her feathers also started breaking in half.


The second that really made realize that something is wrong, she started laying shell-less eggs and soft shelled eggs. The chicken care handbook says its a lack of calcium. Some adviced me that some hens are bad at eating their oyster shells.

I switched some thing around in my feeding routine of my chickens. With first of all adding pure Oyster shells instead of the grit mix I had. I switched out the pellet feed I had from a normal "base" feed to a layer feed.


Another symtom I have reflected back on is that she was very poopy around her vent area. This could have been a early symtom of her illness. Infections or inflammations in the oviduct can present it self with discharge from the backside.

The strangest thing, that I dont know if it was a symtom or not. It could be that she was not feeling well also, but she was over 1 year old and had never been broody. Everyone knows that silkies are known for their broodiness. For a silkie to never have been broody for that amount of time, is strange.


The soft shell and shell-less eggs stopped for a while, but her eggs turned all white instead of the beige color silkies should have. They also got more of a rough feeling among the shell instead of that smooth one they should have. (This is also a symtom I have reflected back on. That I did not realize back then.)

But the egg problems came back just a few weeks later. I tought its still a calcium deficincy. So I tried another route: yoghurt and corn coverd in crushed oyster shells. Like before the problems went away for a few weks with a few days treatment.
I did the same treatment when it came back and like before it went away for a while and then came back.

It went away for many weeks but it did come back and it got worse. I orderd liquid calcium and gave it straight into the beak.

Did this for about 2 days before I actully decied that my knowledge ends here. I need help.

Vetrinarians who takes in chickens are few everywhere. Im lucky to have 4 clincs sort of close to me.
I knew that you could stop egglaying in chickens with a implant. I knew that she needed this. The Vet agreed with me.
I leaved the clinic with the implant and no diagnose what caused it, only a speculation: inflammation in the oviduct.

The strangest thing happend after we left the clinic. 2 days after she went broody for the first time.

The implant would take 2 weeks to start working so could not be that. Perhaps the Vet had a magic touch?

I always let my broodies lay 21 days (with no chicks under). She really needed this break from laying. She also got to be broody with her closest sister.

After this broody session, it was like her system rebooted. She started to molt and it was not a small molt. She lost almost every feather (unlucky enough the temprature would go down to almost -20 celsius around this week).

Slowly her feathers grew back and that crest she had not had in a long time came back. The crest yet again became the next issue but this time the other way around.

She have had such a small crest for such a long time. So now when she got this massive crest, she had a hard time seeing. With this she got depressed.


How did I know she was depressed?
- Standing by her self, not walking with the others.
- Eating less
- Not jumping down from the perch in the morning.

This could easily be confused for sickness but I had a suspicion that it could be the crest. It was easy to test that suspicion: put her crest in a hairbun.
Soon as she could see she started moving around and hanging out with the rest of the flock.

She got "scars" from the massive molt. Some feathers changed color just at the end of them to white. 

I never got an answer why they did this. Some say she has genes from another color, some says its normal for chickens to do this as they age and some say (and what I also believe) that this is a form of "stress lines".

Her illness is still unkown what it could have been or are. 

There is some illnesses that can cause these symtoms, most common are:

  • Salpingitis (which is a sort of inflammation in the oviduct)
  • a fault in the glad that produce the shell.
  • parasite infection.
I have my own speculation (without really knowing) that she may have some sort of hormone imbalance. When she was just a little chick she had many rooster traits, she was to pig to be a pullet. I was for sure that she was going to be a rooster. What got my theory going the most was the fact that she had never been broody. For a silkie, it aint normal for it not to be broody.
Hard to belive she actully has a haircut under that fluff!

Today she just have refilled her implant to stop her laying cycle. Its a low chance the problems would not come back if we stopped with the implant. So she will be retierd from laying for the rest of her life.


When I look at her today, knowing how she looked and felt before, I smile. She looks like a whole other bird. One of her favorite things to do now is her little happy run, when she jumps around like a little chick.

Update 
One day I opend the coop door to a softshelled egg right under Poppi. Her implant had stop working. It work abit over half a year. 
Lucky enough the Vet was fast with ther appoiment and she got a new implant just the day after.

This show that this was not just a temporary problem and that there is still a problem that can be slowed down with the implant.
