Very early this morning an counted out the seconds between crows produced by one rooster. He was crowing at observed rate for some time prior but I began my effort at about 0300. During the 15 minutes of monitoring he belted out a crow every 10 to 15 seconds making for about 5 crows per minute. I could not hear responses of roosters in yard but likely they were doing at least some crowing. Breeding season is about to commence so roosters also trying to attract hens.
