I was reviewing threads and didn't see this topic so hoping someone has experienced this.... One of my hens in particular and sometimes my rooster have been seen up in the middle of the night - 2 am eating and drinking! They seem happy as can be and healthy - we spend a lot of time with them, we only have 3 so I know they eat and drink during the day but not sure why she is up at night. Its the middle of the winter in New England also so its quite cold! Their coop is nice and warm and secure. We have a water heater so the water never freezes up. Any ideas?
