I have a lethargic hen (about a year and half old) that has runny poop (there is a feather that dropped in the end of her poop in the picture). She has a few lice (maybe 3 total from what I saw). She's not eating and drinking much, but I was able to get her to clean a few drops of electrolyte water off of her beak earlier. She seems to be taking long breaths, but I hear no wheezing and she doesn't seem labored for breath. I separated her from my flock last night and have now brought her inside to stay warm. She gets up for a few minutes and then lays down. None of the other hens seem abnormal at all. Any ideas? I've got her in a bin with a heating pad under a towel underneath her. After I'm sure she's nice and warm, I am going to try and give her some electrolyte water and moist cat food.
