Hello all, I have seven young 8 week old Barnevelders that I hatched who range with my adults. I purchased some 16-week birds recently, but had them in quarantine for a week before adding to the group, and they show no symptoms whatsoever. I have them all ranging during the day in a large, fenced yard, and they coop at night in a well-ventilated coop with pine shavings for litter. Two pullets have started sneezing over the last three days. They show no other symptoms other than being a little slower than the rest to come out of the coop in the morning. They eat and drink fine. They totter around the yard as usual. No discharge or runny eyes. I hung them upside down for a couple of minutes each to check for nasal discharges. Poop is normal. So far the only thing I've done is add vitamins to their water. I *think* it's just a cold, but I could use some reassurance. I plan to buy some VetRx today to treat them with. I want to use antibiotics as a last resort. Thoughts anyone?
