I Have A New Chicken...Sort Of?!?

A few days ago my next door neighbor told me that one of my chickens had gotten loose and came into his yard. It was starting to get dark at the time, about 5:00 pm. He said that he would give it back in the morning after he'd caught it. Well, morning came and true to his word he handed me a “Cat Carrier” with what looked like one of my Easter Eggers in it. I quickly put it in the pen with the rest of my birds, and hurried to return his carrier.

Today, a few days later, while gathering eggs I noticed one of the birds staying in the pen, up on the roost while all of the others were playing in the run. I went to check if she was alright when she jumped down and ran outside, so I though that she must be OK. When I turned my back and went back to the eggs she ran back in and back up on the perch. Despite the limited light in the pen I was determined to get at good look at this bird to see if she was OK.

I went closer, she jumped down again, but this time I noticed that the feathers around her neck didn't look as fluffy as normal, and her puffy cheeks were flat. I first thought that she must be sick or molting, but after a little thought, I decided to count the birds. It took a few tries because they kept moving around. The answer to my first question was obvious, how did 19 birds turn into 20?!? Now to answer the next two questions: Whose bird is this, and what kind is it?!? I only know of one other person in the neighborhood that raises chickens, and he specializes in showing roosters. I only raise hens.

She looks like a cross between my Game Hens and my Easter Eggers.

 

Thanks for the responses so far...
