I have a 7 month of hen that started acting strange 5 days ago. At first she was fine, then two of my chickens got out and found some new bales of hay that I had delivered. I got the chickens back in, but that afternoon she started going off by herself. I started watching her and discovered she had diarrhea. I gave her some probiotic yogurt, then by the next day she was acting normal again except for not laying any eggs. She has been a consist layer for a few months. All the other chickens are fine. She hasn't laid in 5 days, and I'm getting a little worried. Is there anything I need to look out for or just wait and see?
