The sad reality of a life cycle is death. Last week we had a time of grieving when our Mama Robin abandoned her nest with unhatched eggs inside. We brought the nest indoors and tried keeping it warm for a couple of days while we discussed how difficult it would be to look after the babies if they hatched. E realized eventually that even if they eggs hatched the babies would probably die soon after as it would be hard for us to keep them fed and warm. We decided that the babies had probably stopped developing. We ended up cracking an egg open and looking at the embryo but E found it quite upsetting so we disposed of the other eggs and kept our nest to use for a science centre in the classroom.
