I just purchased 2 laced winedottes, 1 buff brahamas, and a RI Roo. The hens are around 11 months old and I'm not too sure about the Roo. I purchased them from a place that did not have the greatest conditions... I'm noticing a wheeze and a sneeze in the Roo. Not noticing anything from the hens. I'm wondering if this wheeze will clear up in the fresh air (they will be free range with me) or is there a way I can treat him without anti-biotics. Also, should I go ahead and treat the hens and the rest of the flock? I don't want to use anti-biotics because they are for egg production. Any adivice on helping these birds would be greatly appreciated.
