I have two young chickens, a buckeye who just this week laid her first egg, and an ameraucana who has not started laying. Two days ago the ameraucana started acting lethargic, not acting like her normal energetic self. She's puffing up her feathers, but otherwise looks normal and poop looks normal. I'd like to separate her for a few days and move her into the garage where it's warmer so I can treat her, but I'm concerned about how the other chicken will fare alone during the cold winter nights. I know they prefer to have company, and I'm unsure of how much they rely on each other for warmth when it's cold. It is projected to get down into the teens overnight within the next few days. Will she be ok? Any other suggestions? Thanks in advance!
