Ok so my coop was built about 20 years ago.. So it has no power and its to far back on the property to run a power cord out to it. Last night the temps dropped to about 30 degrees. I only have 3 hens and 2 ducks. The coop itself is large enough to house at the most 15-20 chickens. I'm afraid of them getting to cold at night. I use pine shavings for bedding I was told it helps to hold heat. I'm fixing to build a thing to go across the large open window so I can open and shut it according to what the weather is going to be. I'm also going to be building a pop door for it. My coop is built out of wood and sheet metal or what ever its called lol. Anyway's, I have put in more roosts away from the window but they like sleep in the window roost. (which is right now covered to block most of the wind and snow and rain and what ever else hits us.) I'm worried they might get to cold and freeze to death... I want to do everything I can to protect them from the weather. This is their first winter and I'm worried. So is there anything that anyone can suggest that would work to help keep my coop warmer at night? I was looking for a cheap battery operated heat lamp or just anything that would work to keep my ladies warm! I dont want anything to happen to them. So any ideas please feel free to share. If you need pics of the coop just let me know and I will post them. Thanks in advance for any help or words of wisdom that you all would share with me!
