Just got two new pullets (hatched late July or early August, I believe). I've had them 5 days and they are in quarantine from my other two girls. I have heard a few sneezes out of at least one pullet, but I don't think there is any nasal discharge and they seem to be eating and drinking normally, but I have definitely heard a few sneezes. What else should I look out for and how will I know if I need to be concerned? I plan to keep them quarantined from my big girls for another 10 days. Is that long enough? Is there anything specific I should do at this point? Would electolytes/vitamins in the water help?
