I have a hen that off the eggs sometime in the morning, She was on them at night, I only discovered the nest the past weekend and when candled they were solid black and should be around days 14+. The nest was made on a slope at the back of my mango tree, So when she go off them they slipped down the slope. It summer in my country and its boiling so the eggs were cool but not totally cold. Shes back sitting on them after I placed them again. What are the chances of the embryos pulling through?
