Today, we noticed more tiny cracks appearing in some of the eggs, as well as one or two of the eggs being seen to suddenly wobble. Definitely evidence that some of the chicks are seriously considering breaking their shells and joining us! Two of the Year 5 boys are seen here keeping the water trays in the incubator to the correct level, which maintains the humidity levels in the incubator. Too little humidity, would mean the eggs would harden and then be more difficult for the chicks to break. The boys also checked that the temperature inside the incubator remained at a steady 37.7 degrees. Thank you boys!
