I woke up to a trans chicken

So I was doing chores this morning and heard a weird crow that wasn't from either of my roosters. Turns out it was one of my hens.

I've heard of this happening but I was wondering if anyone knew wether or not I'll have to separate them from my other roosters?

I already have two separate pens since one rooster is larger than average and the other is a bantam.

My now rooster Cloudy is in with my big guy Sunny and I don't want them to fight since Sunny is so big.

Edit for info: Cloudy is 5 years old amd has been laying eggs up until this point
