I have a 4 year old golden comet hen that is normally very active and friendly. She runs to me and follows me around in the yard and keeps me company while doing my yardwork. During the past week after a couple of hours outside she's been wanting to go in her pen for awhile. I later let her out and she's fine. Yesterday (Sunday) she wasn't her usual perky self. She wasn't active. She would stand there and her eyes would slightly close like she was going to sleep and then she would jerk and wake up. She drank water, grabbed her treat but didn't eat it or her food. I felt her crop which seemed full but not hard. I massaged this area and after a few minutes she would drool. She also drooled whenever I picked her up and carried her. I love my little girl and want to help her. Can anyone please tell me what to do?
