It rained here pretty hard for a couple of days and got down into the 50s, and inevitably, everyone got wet. I've noticed that all members of the flock sound a bit nasal, and are sneezing more than usual. In fact, last night one of the girls sneezed and "snotted" on me. The liquid was a clear spray, not goopy. They all have clear eyes, no nasal discharge, all combs and wattles are normal. Other than these two symptoms, they're acting like themselves, running about and chickening as usual. I've already got ACV in their water (this is a regular practice), and yogurt is a favorite treat, so they're getting that. Should I give them electrolytes or Poly-vi-sol or anything else? Thanks for your help.
