I am new to backyard chickens and I have a ? concerning cold weather. It is supposed to drop to 29 degrees here in North Florida tonight with a wind chill in the mid 20s. Even though my 3 girls have a coop I was wondering how cold is too cold for them to be left outside all night? Should I just insulate with hay or should I bring them into the garage? I thought I could put them in a dog kennel for the night. I have 3 chickens that are 4 months old. 1 Ameracauna, 1 RIR and 1 Golden Comet.
