Help one sick chick. And now noticed all the other healthy acting have blue/grey eyes

[Wyorp Rock]

I'm sorry about your sick chick.
The one that is sick in the picture...what does the poop look like?

A good clear photo of some of the eyes that you are concerned about would be very helpful. Breed information too. You mention that their eyes were chocolate colored when you first got them, now they are bluish, depends on the breed, but eye color can change naturally.

For example my PBR babies had very dark eyes the first week, they are now a greenish color and I expect them to eventually turn a bay color. I can't tell the breed of your chick, but some PBR depending on the line may have a blue tint that will likely turn bay/amber. ---Note the eye color change in about 7wks.

At first it’s Poo was watery yellow. With a very strong smell. This morning it was like a normal Poo. Same odor but now it is refusing to eat or drink. They are barnyard mixes. Barred rock Roo. And Orphington‘s , Rhode Island Reds , Americanus Hens

I would agree that clearer pictures of the eyes would help. Ocular Mareks can look several different ways. The pupils may look misshapened or pinpoint, and one eye can look grey. I would do some reading about Mareks first before deciding that you have it in your flock. The best way to get a diagnosis is with a PCR test on feather shafts or tumor samples on a body that is sent into your state vet or poultry lab for a necropsy. Here is some reading:

They all
Look like the last blue eyes showing in the pictures you attached. I’ve read to the point I had to ask. For I read yes a true confirmation and no some chicks eye color can change. I guess the sick chick who is presenting with wing and leg paralysis. And won’t open eyes makes me very concerned

At present I am not handling or working with my stock. I’m having my husband do. He isn’t the kind of person to take pictures. And the sick chick won’t open her eyes enough for me to show. At present all I have is the blue eyed white chick who is acting normal. I just don’t want to touch or feed any of my flock until this one survives or dies. Th sick chick is now refusing to eat and drink so I fear soon

This is the eye of one of the healthy chicks but it was never blue before

I have 15 chicks all acting healthy but now have blue/grey eyes. They did not hatch this way.

At first it’s Poo was watery yellow. With a very strong smell. This morning it was like a normal Poo. Same odor but now it is refusing to eat or drink. They are barnyard mixes. Barred rock Roo. And Orphington‘s , Rhode Island Reds , Americanus Hens

I guess the sick chick who is presenting with wing and leg paralysis. And won’t open eyes makes me very concerned

At present all I have is the blue eyed white chick who is acting normal....But do I have to euthanize all these checks even though they’re acting healthy?

Just for clarification, you only have 1 chick out of 15 that is acting normal. But they all have blue eyes? But, Now you have 1 that has wing/leg paralysis, won't open the eyes and is not eating/drinking?

What are you feeding them?

The symptoms you describe can be a number of things. From vitamin/nutritional deficiency, Coccidiosis, moldy feed to neurological disorders and Marek's. The sick chick, even if the poop is normal, I would consider treating for Coccidiosis or ask your vet to perform a fecal float.

Thank you for replying. Yes only one sick chick but it died this morning. I feed chick medicated feed and I keep a very clean coop. One I’m blessed for I have a huge out building that has a cement floor with windows. And I put pine shaving on the floor and replace often. The food is easy access and same with water. The 15 living all
Still seem to be ok. But yes they all have blue eyes now. So at present I’m just watching them. And hoping that it is not Mareks
