I have a 17 week old Welsummer pullet that recently started crowing. Yes she is definitely a she. I don't think she is the top pullet in the pen. Her comb is small but red and she has red wattles. I think she is getting ready to start laying. Her crow sounds like a rooster crow but not nearly as loud. However it happens quite often during the day and is annoying and if I can't get her to stop I will have to get rid of her.
