The Chick Warmer plate gives controllable low-level heat for up to 25 young chicks. The warmth is from above, so they can move in and out from it as they wish. The height is easily adjustable on the four legs. The temperature-controllable element is totally encased in plastic for safe operation. The domed plastic cover is useful to prevent chicks climbing onto the plate and creating a mess on it. 240 volt. Temperature controller included. **Cover not included.
