My columbia rock hen is about 9 months old. She started laying this summer and has been very predictable. She has missed a few days, including about 3 days recently but now has started back up laying an egg every morning the last two or three days. However, now she is behaving strangely. The most alarming issue is that she is eating poop. The other odd behavior she has is that she used to be my friendliest and tamest bird, but now she acts like she does not want me to touch her. I have been noticing that she looks thin compared to the others (2 australorps & 2 araucanas), but decided they had just passed her up in size as they are still growing and she has stopped. But, now I am not so sure. Her feathers look like they are yellowed and dull. She is starting to look unhealthy compared to the others. They free range most of the day in my yard and always have access to layena crumbles. I give them veggie scraps and a little bit of scratch. You may recall that the elderly gentleman next door was also feeding them and giving them some treats. I have not seen him in a few days, but they were over there eating one day this weekend. I also put down some straw that had been used as decorations at school, but they do not seem to be interested in it. I wondered if maybe I should not have used this straw. Does any of this sound like anything to anyone that I should be concerned about?
