My female duck is now a male duck... is she going to die?

[CaringforWildlife24]

Hi guys I haven't been here in a while but google has NOT been much help so I wanted to reach out to other duck owners for their opinions/experiences. Sorry the title is so dramatic, but that's pretty much the gist of what I am asking.

Some information, I have a female mallard named Billy, she is 7 years old, has not laid an egg in about 2-3 years, and a couple of months ago she began her transition to a male mallard. I know this can happen in some birds, so I wasn't too worried about it considering she is old and has not laid an egg in a long time, I figured her ovary just retired and her body thought she was a male. She is acting normal, happy, eating well, but a friend of mine informed me she saw an article saying that mallards who transition to male do that due to their ovary being damaged or infected with an illness, and it will ultimately kill them in a few months.

Now I don't know how true this is, but I also don't want to take a risk. Like I said, she is acting COMPLETELY fine, but I have no idea what is going on internally. Has anyone experienced transgender ducks before? Will it kill them? Any information will be helpful! Thank you so much.

Will post a comparison image below so you guys can see how she looks now vs before New billy on the left, old billy on the right!
