Sick hen: Laced Wyandotte, about 8+ months old, bought as a pullet. Rest of flock: 8+ months old, Production Red, Ameraucana Rooster: 6+ months old, Barred Rock She stopped laying over a week ago, could be longer because she was acting fine so we thought maybe she was just laying elsewhere (we free range). Still seemed fine. But every day she seemed less and less a part of the flock. She got less and less active and just kept to herself. I finally noticed that her dropping were runny and making a trail down her backside and her wings were drooping. I have her isolated now. I don't have a vet near me but the guy at the feed store recommended Corid. I started googling and just can't seem to tell if this is the right treatment or not. The other chickens are still acting ok though their dropping were starting to get runny. Theirs are still a dark color. Hers looks like scrambled eggs: white with some yellow in it. I have only been dosing for a day so no change yet. She seems too skinny. I thought she was pecking at food before but when I really suspected she was sick and started watching closely, I didn't see her eat or drink on her own. I'm pretty sure she is dehydrated and malnourished. I started giving her water with an eye dropper and just got a vitamin mix today and started dosing with that. She still isn't drinking or eating on her own. She just hunkers down in the crate, though I do catch her standing from time to time, it isn't for long. Her wattle is red, no feather loss, her backside seems a little red but her vent isn't prolapsed or anything. As far as I can tell there isn't an egg stuck. At this point her crop isn't totally empty but there isn't much in there. So far, I've given her a little epson salt treatment, dosing with Corid in her water for barely 24 hours, plus the vitamins started today. I bought, but have not used, antibiotics and dewormer. I'm not sure if I can mix antibiotics with the Corid and I don't want to unless I know it's safe and would do that to cover all bases. I'm worried for the rest of my flock. I'm very attached to the rooster and would like to figure this out so I can insure the safety of the others.
