I have a Brabanter who was born in Feb 2012 and she was wobbly to begin with but with some. Electrolytes, she improved but always seemed to lag behind our other 3 hens of the same age. Here recently, I've noticed that with minimal stress she begins open beaked breathing and her breathing sounds "tight". Last night, I also observed her laying with her sisters and you could clearly see her chest rising and falling with her breathing where you didn't see that with the others she was laying with. She is eating well, drinking well, playing and grazing (on grass) fine. I am stumped. Because she is acting fine, I want to say no big deal, but when I saw her breathing next to the others last night, it's clear that there is a problem. There is no discharge from her nose, eyes or beak and her breathing just sounds "tight" but no real wheeze. I've only heard her sneeze one day but not regularly. Any input would be helpful since I am new at this and don't want to be missing something important. Thanks everyone!
