So my bantam Sultan hen starts wheezing yesterday afternoon, I mean a loud inhale and exhale wheeze. She wasn't doing it in the morning when I let everyone out, so what the heck? I picked her and her nostrils were packed solid with mud (we've had a lot of melting snow resulting in a mud bath here). I brought her in and cleared and rinsed as much mud as I could, but she was still having trouble. So, how much do I love my girls? I took her into the bathroom with me while I showered, ran it really hot and the humidity softened up the rest of the blockage and she started breathing normal. I kept inside all night under a heat lamp just to make sure she was alright, and she was completely fine this morning and is now back with flock. So, just thought I'd share this, check their nostrils if they all of a sudden have trouble!
