I just purchased a Dark Brahma hen on Saturday at the Ohio Nationals Poultry Show. She seemed very healthy and alert. When I made the puchase I purposely looked her over and her eyes were bright and alert, she walked good, no nasel discharge, poop in cage appeared normal, etc... After I got her home I put her in a section of the run away from the rest of my flock so she could adjust. She explored her run, drank and ate. After she ate I noticed she was coughing/sneezing and bubbles were coming out of the corners of her eyes. No nasel dicharge and seemed fine in every other way. I took her in the house into a pen and for the rest of the day and evening I didn't hear her cough or sneeze at all and no eye bubbles. Then Sunday morning she seems just fine and I take her back to the run and as soon as she eats she started coughing again... i didn't notice eye bubbles this time. I went ahead and left her in the run for most of the day and on occasion I'd hear her cough although it wasn't too much. Then last night I put her back in the house just she'd have a place to sleep away from the coop and the rest of my flock... never heard her cough at all last night. This morning when I went and checked on her she seems just fine but she did cough again once that I heard; no eye bubbles or discharge. It almost seems like she coughs mostly after she's been eating or like something is in her throat. I dont know how to tell if it's that or a cold or something else and I'm not sure if I really need to keep her away from the rest of the flock still. Any advice?
