I got 2 new chickens around 3 months old on June 7th. About 5 days later, I noticed that most of my chickens were making a sneezing or coughing sound and shaking their head when they would do it and sounded like they were wheezing. They also had runny yellow poop. Only one of my new baby chickens has a runny nose on just one side of their beak. I gave them all some vet rx and added a probiotic water enhancer. Their symptoms faded some but I still noticed them. I added tia guard to their water for 5 days and they're doing better but still occasionally sound like they might still be sick. And, my baby chicken still has a runny nose on one side that is just now starting to stink. They all act like they're fine and are eating and drinking ok. Should I just keep waiting it out to see if it will go away or is there an over the counter antibiotic that I can give them to make it all go away for good? I'm new to the chicken game so I'm not really sure what to do and I don't have a vet for them. Thanks for your help!

Where did you get them?
Coryza smells bad so I'd suspect that.
Unfortunately, if it Coryza, I'd recommend you cull, sanitize and start over next year, it's highly contagious and they'll be carriers for life. I'm so sorry

I'm sorry your chickens are sick. For the future: whenever bringing new chickens onto your property, quarantine them for about a month and be very cautious about cross- contamination. So always care for your own chickens first and change clothes and shoes between flocks. Me, I would wear gloves and maybe a mask between flocks and have a dedicated pair of shoes for the new birds. If, after a month, the new birds still seemed healthy, I would begin integration proceedings. But tbh, I keep a closed flock. The only new birds that enter my property are baby chicks from a reputable hatchery. I hope @nuthatched is wrong but she's pretty smart so I would not bet against her.

Respiratory diseases are contagious and make most carriers for life. Some unscrupulous sell birds who have been exposed to diseases, and then you can easily bring in a disease such as coryza, mycoplasma gallisepticum (MG,) or others. If they are together or near other birds at a sale or swap meet, the healthy birds can be exposed to diseases that way. When they show symptoms a few days later, and you haven’t quarantined, they can infect all of your birds. Tiagard can treat MG. Have you had a sick bird before. If you lose one, send the body to your state poultry vet lab where they can do a necropsy, and tell you what illness you are seeing.
