Crowing
It's nice to be able to check on them if I hear strange noises during the night.
Most of the time I can see them out of the windows.
I put on one of those Alexa devices in the henhouse (got them on sale) and I used them as baby monitors for a while. I was getting up several times a night to check on them, so this helped me let go a little.
Cameras are a better idea though. I often just hear rustling and then get out there to find an inter-species war. (ducks vs turkeys)
