I know that my chickens can handle the cold. Obviously many of you have happy chickens in much colder climates than mine (I'm in Louisiana!). My only concern is the sudden temp change for my chickens. We have been in the 80s lately during the day, 60s at night. Tonight we have a freeze warning and it will get to 30ish in my area and stay below freezing for 3-4 hours. They were born in April so this is their first freeze. My chickens have a coop with protection from wind, but no insulation or heat or anything. Do you think I should worry about this sudden change in temp? I have 4 hens and 1 young rooster. Thanks!
