That all depends...does she have discharge from the nostrils? Is it continuous or occasional? Any other symptoms like pale comb, lethargic, not eating, diarrhea? If it is just occasionall sneezing, then I would say she is probably ok. But watch her closely and if it gets worse, then I would possibly do the antibiotic thing.
well i have only noticed it today no discharge her comb is actually quite red but shes molting, and she probableys eats the most she gobbles down bred its her favouraite
Sounds like she is fine. You could offer some vitamins to the water and a daily hard boiled egg will add to the protein of her diet and help the molt out.
