Put a coat and glove on and slowly and carefully reach under to feel for the egg. Normally when my hens start talking it means a poult has hatched. But if all the other eggs were infertile, it is more likely a rotten egg.Thanks. I tried to see the egg but my hen has it under her chest puffed up.
She keeps clucking every so often.
Just a bit ago she puffed up at me did a cluck and click.
