Wow. I knew dominant hens could become more rooster-like, but I didn't realize by how much. I did some research and apparently mature hens have one ovary and one ovoteste that remains dormant. Sometimes the ovoteste develops later in life and you have a chicken with both male and female organs, called a Pollard. Usually infertile and may or may not lay eggs, with some sources claiming that the chicken can actually cause some fertile eggs to show up in the flock.
I took a closer look at the hen today and sure enough she is growing spurs--they are about 1/2 inch long already. Her comb and waddles are bigger and redder than before and she has been trying to crow so much I had to put a rooster collar on her. She also went from laying 6-7 eggs per week to about 3. I guess I'll have to wait and see what happens. I sure hope she doesn't stop laying altogether.
I guess this explains why she has such pretty neck feathers too...none of the other buffs have such long and shiny neck feathers. I am just blown away by this. A few days ago I didn't know something like this was even remotely possible.
