Hello, We in western Washington are in the midst of a snow and ice storm. My yard has a foot of snow on the ground which is highly unusual for my area. The snow has been accumulating for a couple of days now and I've noticed that there aren't any chicken footprints leading to the chicken's water source. My hens have spent the last few days hanging out in the coop because of the weather. Do you think they are eating snow for water or could they be dehydrated? The water is not frozen, thanks to a birdbath heater but they don't appear to be drinking. Should I be concerned? Thanks for any info!
