Blood in poo

[Chrisd01]

We have 3 chickens about 26-28 weeks old & ive noticed that one of them has done a solid light brown poo with what seems like a tail of blood not a large amount but a spot. The blood is quite dark red. We use diatom in their food (a small amount) plus some tonics in their water.
Has anyone any ideas?
They seem themselves & are not off their food. Although they're not out as much now as we're back at work & are letting the lawn repair itself

If you are seeing blood I'd treat them all with Corid and the sooner the better, you may have a case of coccidosis going on. Better to be on the safe side. If that's what it is they often won't show any visible sign of illness until they are very, very sick. By then you likely will not save them. You put it in the drinking water, treat them all for 5 to 7 days, make it up fresh every day. Corid can be found at feed stores, usually in the cattle dept. You are looking for Corid 20%, labled for calves. Liquid is also available. Dose for powder is 1/2 teaspoon per gallon of water for 5 to 7 days. Not sure on the dose for the liquid. Don't let feed store employee's talk you into Sulmet, it's very harsh on the birds and it does not treat all strains of coccidia.
