Regulating the humidity of a brooder can be a challenge， but the Brinsea TLC Advance Bird Brooders Humidity Pump automatically regulates humidity for you. When paired with the Brinsea TLC Advance parrot brooders， this pump maintains the humidity right at the level that you set， helping to prevent dehydration of your feathered friends. This pump includes an external water reservoir， to minimize the chance of the water inside the brooder holding bacteria. This unit stands beside the brooder， and an electrical lead and water supply tube connect to the brooder. You can control the humidity settings with the brooder’s digital menu， and the digital display continuously shows the relative humidity.
