With the water freezing, I'm worried about dehydration. If I bring fresh water every morning (say 8:30 am), and assume it stays liquid for several hours at least, do they need water again before bedtime? At this time of year, it's dark by 6 pm. If this winter is like last year, there will be many days where the water won't freeze during the daylight hours. But it probably will at night. My coop light comes on at 5 am. This morning they were quite thirsty by the time I brought water. I felt bad. But it's not as if I can wake them up for a drink before they bed down. And I'm certainly not getting up at 5 am to bring them water. Do you think they'll be ok?
