RE: Hen with a red head?
Yes, I'm sorry. I didn't mean to state that a hen couldn't gobble at all. It is, however, quite rare I believe, and definitely does not sound anything like a tom's roar. The only one I ever heard was sounded like a very young jake...quite incomplete with decreased amplitude and much shorter (maybe .5sec) duration.
They do strut all the time. I find here in New England much moreso in the late summer/early fall, when the hens are still fighting for their poults.
