I just ordered myself one of these. They look really smart. I think they are for up to 20 chicks. You can raise it up as the chicks grow. I think they have three height settings. Can't wait for it to arrive now. And yeah, it was £30 including postage, compared with £20 for the heat lamp thingy and £5-10 for bulbs, which are always breaking or burning out anyway. And they are 250W, compared with the EcoGlow which is just 18W, so they'll save a lot of electricity.
