I have a Silky (age unknown, I do know she DID successfully hatch eggs for someone else) who is sitting a clutch of eggs right now. It has been about two weeks since she started. I know they have to leave the nest to eat/drink, but this one walks several laps around the coop before she goes back to her eggs! She makes a clucking sound while she does it, is this normal behavior? The only other hen I've had hatch out eggs was free range bird who did it in secret.
