Hmmm. Did a search on line for Ancona Roosters, as I'm not real familiar with them. The roosters in the photos seem to have larger tails and combs than the photo you posted. Perhaps you have a dominant female?
Do females typically mount other females? She has always been bossy and the most independent but this morning ( and most of the day ) she started chasing and trying to get on my BA who has the reddest cone and wattle.

Her tail seems to be growing more upright but hasn't started any of the big curved feathers.
