Hello All, I recently found/cought a chicken in my neighborhood, what appears to be a beautiful young Wyandotte. She is so charming and funny I decided to build her a coop and get her some friends. We are animal lovers and vegetarians in my house so she hit the jackpot. That was a few weeks ago. Then a few days ago I purchased two more 4 month old hens from a local farm store, a Blue Cochin and an Ameraucana. I figured since they are all a collection of strays and they all looked healthy, and I have no experience with birds, I let them all meet face to face. Now a few days later the Blue Cochin is sneezing, has nasal discharge (which smelled foul when I cleaned it, or it could just be that she's dirty from her muddy old pen), and has a gurgling sound in the throat when talking (Infectious Coryza ?) So I hopped on the net, found all the cold type posts on BYC, read them and now feel like I have doomed the other birds and that the Cochin must be carrying MS or any of the other terrible things that it sounds like most young breeder bought birds have. When I picked her out at the farm store she was in one of 5 pens, each with about 30 mixed birds, and it was wet because it has been raining and cold here everyday for the last month. The Ameraucana was in a pen in a separate building and shows no signs of illness at all, and other than the cold symptoms the Cochin is alert, eating and drinking and scratching around like nothing is wrong. My first question to the pros is what should I do now? The sick bird is separated, I cleaned the nasal passages with a warm wet cloth and applied vicks to the comb and waddle. My next question that I couldn't seem to find an answer to in all of the other very helpful and thorough posts regarding these symptoms and the various diseases and viruses that cause them is, which of these can the birds live with or get over, and which are a death sentence. A few that jumped out at me were . . . Mycoplasma Synoviae (MS) Infectious Coryza Chronic Respiratory Disease (CRD) Mycoplasma Gallisepticum (MG) If anyone knowledgeable wants to add to this list and add recoverable or not after each that would really help us total novices who have read the doom and gloom about these terrible chicken illnesses and now feel like having healthy birds is impossible Thanks to all in advance! P.S. I read Threehorses reply to a post regarding how chickens get respiratory illnesses and found it very helpfull and hope Bluebell the Blue Cochin has something simple due to a worn down imune system, fingers crossed.
