That was a good positive story to read--Thanks for sharing!so a few days ago in the paper there was a story about this family that was given a hen that did not lay much anymore to eat, well the lady just could not eat her so they kept her in their basement. well one day the family woke up because the hen was freaking out being as loud as she could, turns out the house was on fire. so they saved this hen and the hen saved them. cool story huh? edit found the story http://www.huffingtonpost.com/2012/12/28/pet-chicken-fire_n_2376501.html
Probiotics via buttermilk or unflavored yogurt or a probiotic supplement, as well as black oil sunflower seeds (which you can get in small quantities in the bulk food section at Winco Foods) are my best suggestions for cold weather foods, in addition to high-protein food in general.
I'm also running a regular lightbulb at night in the fairly closely enclosed area near where my chickens sleep, as well as leaving the nest open for them to sleep in it when they want to.
Best wishes to all with this cold!
