I have a one and a half yr old black star hen that woke up this morning sort of lethargic, so we picked her up to look at her, and she's sort of wheezing a little and she sneezed. We gave her some Vet-x in her mouth, and when I put her back on the ground, she lost a bunch of feathers and I wasn't holding her tightly. We also have a little silkie hen, same age that was making the same noise, so we gave her some Vet-x as well. We have had a cold snap here, going down to about 45 as the lowest for a few days, but other than than, they've been fine. I've seen some suggestions of Coryza here, and wasn't sure if that might be my problem. I have some baby vitamins from a previous illness and was going to give them all that with some yogurt as soon as I get some. Oh, also, I didn't smell any odors. Does anyone have any more suggestions on what might be the problem and what to do? I appreciate it as I know there are many people with questions, but I'm worried about my girls too. Thanks so much.
