This was what my barred rock pooped last night under the roost. There is a strange gunk in the middle and I'm not sure what it is. I think I've seen bits of it in her other poops during the day occasionally. Overall, her poop has been a bit smaller and more white, but nothing too abnormal. Her behavior is not much different from normal, although her appetite is just barely less, but I might just be imagining it. She still eats plenty enough though. On an important note, she is a year old and has never laid an egg. Am I just being paranoid?
