I have three bantam Favrolle hens living in a 3 by 3 coop and now that winter is coming up here, I'm not sure if I should put a heat lamp in my coop. It gets down to 10 degrees around here during the night. should I get a heat lamp??
i wouldn't. You want the chickens to adjust to the cold...which, 20° seems pretty cold to us, it isn't for a chicken. If you have an ice melter for your waterer that will bump the temp up enough. As long as they are dry they will be fine. Just watch them and see, if they huddle together all day long and appear distressed they may need improvement but I think chickens love the colder weather. Just saying, down jackets on and all.
