Found chicken looking miserable, standing in a little snow. Beak dripping, wheezing. Called chicken friend; said nothing could be done. No point going to Vet. Brought her indoors into puppy crate, fresh straw, good, water & waited for inevitable, which never happened! Third day saw her drink, then eat. I've kept her indoors now for 3 days, changing straw, food water frequently. Turnaround is amazing! When is it safe to return her to the coop with other rescues?
