I keep my rooster in the house on weekend mornings, so his crowing won't disturb the neighbors who might be trying to sleep in late on the weekends. This morning my rooster crowed incessantly, wanting to be let out with the girls. It got me to wondering whether a rooster can wear out his crowing apparatus, get a sore throat, or even get a throat cancer or something from excessive crowing? Does anyone know of any research I could read on this topic? Once I let him outside, he hasn't crowed once since.
