I am not a big soda drinker but I googled it to see if I could help. Now wine on the other hand....
I would quarantine her and watch and wait. If it is respiratory, my understanding is that if one has it, they have all been exposed to it. If she ends up have a respiratory illness, you can choose to treat her then. Then keep a closed flock so you don't infect any other birds. Hopefully it's nothing. Will you keep us posted?
Tylan 50 administered in the breast was a wonder drug for me just like CMOM suggested. It doesn't cure your chicken but does knock out symptoms. I thought it was every day for 3 days and no more than 5 days so I'd search it on the forums to double check. I'd keep them separate til you don't see anymore symptoms in the chicken.. Could be up to two weeks is my best guess. I have done a ton of reading but can't replace tons of actual experience people on here have. The professor in charge of poultry at University of Florida Vet School I talked to never uses antibiotics on his personal flock and lets nature weed out the weak. He also does not kill sick birds or the entire flock if a bird gets CRD. Good luck and keep us posted.
