I wasn't expecting any of my cockerels to start crowing for maybe another 2 months or so and this morning one of my cockerels was just crowing up a storm. Being that he just started crowing he sounded like he was being strangled. Last night my daughter and I was cleaning up the chicken house and changing the pine shavings. I am in the chicken house pretty throughout the day so I know that none of the cockerels had started crowing yet. Well I have some cockerels that have started trying to mate with the pullets. Only one of the cockerels have red wattles and comb. The others that I suspect of being cockerels has big pink wattles and combs. Isn't 9 weeks pretty young to be crowing? I was thinking they started around 16 weeks or so.
