4 month old chickens with bloody poop

[bpayne1973]

Hello, I’ve got at least a couple of my 4 month old chickens that I incubated pooping blood. I integrated them into my flock by first having them in the run in a separate enclosure for 3 weeks. For the last 4 days they’ve been with the rest of the flock and I’ve noticed for 3 days that I’ve seen a bloody poop here and there. No one is acting sick as they are all running around playing as usual.
My run is open with no cover and has a dirt ground (working on finding a way to fix this as it’s a large area with huge roots in the ground). I do live in the Florida panhandle and it’s our rainy season so it’s pretty damp out there. I do have Corid on hand that has been open for some time but not expired. It has a smell though that I’m not sure is normal (slightly like vomit actually) so I haven’t used it, nor do I have confirmation it’s coccidiosis. There isn’t an avian vet near me that I can take any of my chickens to either. Looking for advice as to whether I should administer Corid and if my Corid should be replaced.
I appreciate any guidance you can offer. I’ve had chickens for 4 years and this is my first experience with bloody poop.
Best,
Brandy

Forgot to mention they’re eating Nutrena Naturewise Feather Fixer (that’s what the adults eat) and the last of the Kalmbach unmedicated chick starter.

I did also just finish a round of aquasol because I found worms in someone’s poop. After that round I’ve done about 5 days of poultry cell.

Get some Corid asap and get them started on it. Coccidiosis is very common, the medication is very safe and wouldn't hurt them even if it was something else, but coccidiosis can kill them.
Dosing is 1.5 tsp of the powder or 2 tsp of the liquid per gallon of drinking water, make fresh daily. It should be the only water they have access to during treatment and treat for 5-7 days. No vitamins during treatment as that can possibly make the medication less effective. If there are any that are acting lethargic, sitting fluffed up, not eating or drinking, or that you know are having the bloody poop you can also give them an oral dose once a day for up to three days, dosing for that is by weight and instructions are here, you give the oral dose in addition to the medicated water:

You can use either the powder form or the liquid form, most people prefer the liquid for convenience but either will work...
You can separate the young ones and treat just them if you want, or you can treat the whole flock (which is probably what I would do), it's very safe and won't hurt anybody. Your choice.
