My hen is becoming a rooster?

[MokiYoki]

So I have a WFBS hen, she was a great layer but I havent seen her eggs lately, which isnt that unusual as it is winter anyways.
But Ive been noticing her mounting the other hens, and today her comb unflopped!
She seems pretty healthy but her comb does look a little paler than the others. Should I assume ovary infection and treat her with antibiotics?

It sounds like she's taken over the role of rooster, which isn't terribly unusual in a flock of all hens. I've even had a hen crow - yes, a full out crow!! If you're allowed to have roosters adding one might bring her back to her productive laying self again and relieve her of her self-imposed role of leader. It sounds like she's perfectly healthy and may be about to molt - so unless you see some really worrying signs like a lash egg or icky discharge, or she acts sick (puffed up and uncomfortable looking) etc., I would forgo antibiotics.

She is in a breeding flock. There are 2 active roosters plus a gaggle of teenage boys (many of which are her's) as well so it cant be that. I will keep an extra close eye on her for anything that looks even remotely sickly, but so far she seems fine, her and her offspring are my most healthy and active.
As a matter of fact the first I spotted her mounting a hen was directly after her man had dismounted.
