Hi everyone, I'm new to backyard chickens. I just got 4 Red Sexlinks a couple of months ago. They're now 7 months old. They've been giving me an egg a day each for the past month or so. Two days ago I noticed something that looks like small dark blood clots in some stool. In the past couple days I've found 3 stools with the same substance. One of my hens is defintely ill. She has been dripping (or vomiting) water from her beak, has been lethargic, and her vent is pulsing with a raised tail. She hasn't been eating much either but has been drinking water. Her comb and waddle has become a little pale too. Alll she does is sit down and pulse her vent with her tail raised. It's as though she's trying to give birth. I don't think there's an egg stuck in there cause she's been giving me one a day until today. Any ideas? Please help. It's so sad to see her so uncomfortable!
