I put one of those flameless candles, the kind with a timer, on the back on the back of the toilet so I wouldn't turn on the bathroom light in the middle of the deep, dark night any more. Turning on the regular light was triggering a cacophony of crowing from the coop, which is in the yard on that side of the house.
If I am on the front porch with friends, talking, the roosters will crow. In this instance, the geese will also honk.
Everybody makes noise when my alarm goes off at five a.m., even though all the windows in the house are closed. I don't know HOW the flock hears it!
