I believe she is a americauna mutt. I rescued her from our local SPCA. They did not have any info on her. She is full size, I believe she is at least 8months to a year old.
She eats layer crumble that I feed the others. Although she seems a little thinner than the others. But not by much.
She does not have much of a crown like the rhode islands...could that be an age indicator? I have been told it is a breed characteristic.
I'm not sure if she is checking out the nesting box. But she seems to spend more time in the coop than the others.
I will post a picture when it is light outside.
