My son hatched eggs 3 years ago for his science fair project. We used refrigerated versus non refrigerated eggs as our test and the hypothesis was that the refrigerated eggs would have a lower hatch rate. My daughter wants to use hatching chicken eggs for her project this year but we need a different hypothesis so she's not just copying her brother's project. I figured all of the great chicken minds here would be able to help. Who has some ideas? It must have a testable hypothesis and follow the scientific method.
