Thank you both for your advice. I've ordered some meds and vitamins that should be here in the next 2 to 3 days. She is doing much better this morning after saying in the warm house last night. She's drinking, eating and wheezing much less although its still there. I'll keep her inside for the next week or so depending on when those meds get here. We're also expecting more storms here in Northern California over the next week (we'll take the water) so I'll keep her inside and dry.
To answer your questions, she's only been like this for a day although she's always been a bit congested. She get huffing good after running across the yard after her flock mates. She's a bit of a princes, for example she can't be bothered to scratch on her own when the other hens are turning up the soil just fine for her. That's not to say she never scratches, just that she'd prefer some else to do to work. I've never had my hens checked for worms but I scrape their poop board almost daily and I've never seen any signs of worms.
