The Brinsea Octagon 20 Turning Cradle will convert your Octagon 20 Eco or Advance from a semi-Automatic egg incubator to a fully automatic egg incubator.
The Octagon 20 Eco or Advance will sit inside the Turning Cradle in which it is rocked from side to side. During the hatching period, the Turning Cradle can be disabled by simply removing its power source.
