How many days is she already brooding the eggs? When was the due date? They will usually hatch after 19-23 days depending on the egg size, freshness of the eggs and brooding consistency of the hen.
Did you candle the eggs at all to check on their respective development?
You can use a dog nail...
A little rooster pedicure can help to reduce hens' feather damage and prevent cuts.
How many chicks hatched? Unless it was a staggered hatch they should be out and about with momma hen by now.
It is! They have an incredible range of vocal expressions and so many nuances that one will only experience when they have chicks.
Fingers crossed that everything goes well. :fl
Cooing means that she is talking to the chicks in the eggs encouraging them.
Although the suspense might seem unbearable, just let her do her thing and wait.
