I have a 2.5 year old Easter Egger that has fluid coming from her mouth. I noticed yesterday that she was making a weird sound and was just standing there with her mouth open. I brought her inside and have been keeping an eye on her. She's very alert and acts almost normal. I felt her crop and it's empty. She had a little brownish fluid that came out when I was feeling it. Her poop is normal. I had given her some food when I brought her in and I believe she did eat some yesterday. I don't think she's eaten anything today, though. I looked in her mouth and didn't see anything. Does this sound like sour crop or could it be something else? Thanks in advance.
