Ok, so I have been at the backyard chicken game since June of this year. We started with 6 Chicks under a heat lamp. We lost one early (natural causes I'm guessing no signs of illness), One was taken by a hawk, and 2 of the "pullets" turned out to be roos (can't have them in neighborhood). So after sending the roos to live on a farm. We went back to our feed store/chicken farmers and bought 4 new birds Yesterday. 3 chicks 6-8 wks and a 16 wk old Cuckoo Maran. On the hour drive home they all rode together and I thought I heard sneezing. Once Home I noticed it was the Cuckoo and her eyes looked a little watery and her nose was running. I also hear a little rattle when she speaks. I didn't see any of this when we were loading her into the car. This morning when I checked her she was blowing a bubble out of her nostril. EEK! The birds they sale are all advertised as vaccinated as well. She is quarantined in the garage for now but separate from the other smaller chicks (as far as possible). I also have her on medicated chick starter. Her color is good. Her poop is perfectly normal. She is eating and drinking fine. Her energy level seems normal, alert and active. There is no foul smell. Our weather has been completely terrible and very very wet here. Is there any chance she has something less serious than a major respiratory problem? Do chickens just get sinus infections? For me its a hobby flock for my family 6 birds max. I have been reading terrible stories about terrible respiratory diseases. Where do I go from here? What do I watch for or treat? I am very bummed with the bad luck I have been having and feeling like I am trying so hard and getting no where. All I have left is two 14 pullets. It really feels like we will never get to enjoy the fun of having chickens…or fresh eggs ;/ Thanks in advance for the help!
