I think my 6 month old black laying hen is sick. About an hour ago I noticed she wasn't really scratching around like the other hens and when I walked up to her she didn't really move. I've separated her from the rest of the flock and she's drinking a lot of water, not really eating. She's just standing, letting her head slowly fall and her eyes are closed. As if she's falling asleep standing up. Maybe has a fever since she's drinking so much water. Any ideas? Anything more I can do? I don't have a vet nearby. Do you think she'll make it?
