i have a group of 20 chicks. i noticed that one pooped out bloody stool ONCE about a week ago, so i rushed to the store to get some sulmet thinking it was coccidiosis (freaking out). no other symptoms though, just the bloody stool. all of the other birds were totally fine, and no blood in their stool. today was their last day on the sulmet, and after a whole week with no more bloody poops from anybody, including the only bird i'd seen actually poop out the blood, he made ONE MORE bloody poop. still no symptoms though. it's weird. i decided not to try sulmet again because i want to find out if that's what's wrong for sure, or wait until he or the others do exhibit symptoms. yes, they eat medicated feed. they have their whole time they've been with me. the bird that pooped the blood is about two months old, and we got him from a breeder, (we got him at 4-5 weeks) all but four of the others are from hatcheries. please tell me what you think about this, and what i should do. thank you!
