Eglu Cube, auto door, walk in run for sale South West London

I'm trying to get my Eglu to stay warm, because it'll get incredibly cold at night due to the massive storm. I have currently the biggest Eglu, but a different run with it (a dog run). I managed to remove the wind from the run and covered the run in plastic and tarps to make it warmer, but it's still pretty cold. The Eglu itself I haven't found a way to keep warmer outside a tarp over the coop that keeps heat in. 

 

Can anyone share tips on how to keep the run and the Eglu warm for the chickens?
