I have a broody hen sitting on eggs, and I don't know if they have gone past the hatch date or not! I did the 'float test' and all the eggs floated fine, but I could not see them moving. I shone a light through them and they just looked sold inside. How can I tell if there are live chicks in there, or if they are dead or not going to hatch? There were lots of eggs in this nest, shared by 3 broody hens. 2 batches of chicks hatched about 5 days apart, and the other 2 hens are looking after the chicks. But this one hen is still on some eggs and its been another 5 days. I don't want her to get sick from brooding too long. If the eggs are not going to hatch how long till I can tell they are bad?
