Hello In the last several weeks our hen Danica became broody so we decided to put 4 eggs of my other hens under her. Just yesterday we found a little chick chirping about under her, but she is still sitting on the nest. The 3 eggs are not yet hatched. I was planning to put her inside a small quarantine coop with her chicks to keep them safe from harsh weather and predators, but since the eggs have not hatched I let her stay in her nest in the bush until they hatch. But it's been a day and the other eggs still have not hatched. I'm worried about the little chick because we are having some harsh weather here. It's been 22 days of incubation. How do I know if the eggs are still alive? Thanks in advance!
