Hen was healthy yesterday. This morning, didn't even want to come out of the coop. When she finally did she just stood in one place. We have separated her already just in case. Her feathers are all puffed up making her look bigger than she already is. She hadn't raised her tail feathers all day. Just standing with her but down and her neck retracted. No fever but hasn't pooped since she been isolated, 7 hours. She's not really eating or drinking but I did manage to get a few drops of water into her a little while ago. She is about 8 months old and I have no idea on weight. I can say that she has just recently started laying. With that in mind I felt her underside to see if she was egg bound but I didn't feel anything. As for her crop, I'm not sure what it normally feels like. She's definitely the least human friendly bird we have so when she allowed me to pick her up without fuss, it knew she wasn't well.
