She may have a malfunctioning ovary that causes her to act more masculine, but that bird is female.

Leghorn hens have crazy big combs so that may be throwing some off. Also, hens can cock-a-doodle-do as good as a rooster. Her feathering says the most...

A very likely explanation to her behavior. 'She' probably started life as a hen but may be going through gender transformation because of ovarian problems. I saw the same change in a friend's RIR 'hen' as she aged.
