Help! Brought home new chicks, now all chickens are starting to sneeze.

Last week Wednesday we went out and bought five chicks, 4/6 weeks old. They all appeared healthy, the guy who sold them had a very clean organized setup with clean water and clean bedding.
I brought them home and put them in a small cage within my coop. Woke up this morning to find one of my pullets hanging around on the bar sleeping - and all the rest had come down.
She had a runny nose, was sneezing every so often. I put her in a cage inside my home, gave her some water with some garlic, oregano oil and herbs.
She appeared normal otherwise and was eating and drinking. Seemed a little more tired and one eye kept closing more than the other. Not watery at all and nose had clear discharge or bubbles when she sneezed.
Just went into the coop and found another who was starting to sneeze. But no runny nose yet.


What do I do?

It sounds like they have been exposed to a respiratory disease such as infectious bronchitis or mycoplasma gallisepticum (MG.) If they develop bubbles or foam in an eye or swelling of the eyelid, that is more a sign of MG. Do you have other chickens? Can you get Tylosin, Tiamulin, or oxytetracycline? Those can treat supigns of MG. Infectious bronchitis, though is a virus, and lasts around 3 weeks. It has to run it’s course since there is not treatment. Make sure they have fresh air and keep their area clean because droppings may affect their breathing. Clean off beaks if needed. Fluids are good, and nothing but clean water is necessary. Offer food often and fresh moistened feed is good.

Yes, I have 20 other chickens.
The area is all open and spacious, and I don’t see any bubbles or foam or swelling in her eyes, but one is closed.
Thank you.
Should I keep her separate?

They have all been exposed already, so I would leave her where she is. Have any of your older chickens ever had a respiratory infection in the past? It only takes a few days after exposure for chickens to show symptoms of respiratory diseases. If yours have never been ill, then they may have been exposed just before they came to you. Chickens with infectious bronchitis virus can be carriers for 5 months up to a year after recovery.

Older chickens have never been ill. I’ve had them almost a year.
I separated her this morning, so I guess I’ll put her back.
