I have a Marans roo that is sneezing and I think he has a respiratory disease, I think i am going to cull him though. But that isn't the bad part I also have a Old English Game Bantam roo that I think had a respiratory disease when he was younger, I gave him some meds and he cleared up. He was sneezing and wheezing at the time then it may have happened again but it cleared up by itself if he had it that second time. Is the OEGB a carrier of a respiratory disease.
