I picked up 4 chicks from a feed store yesterday the oldest he said were around 4 weeks, and the other 2 are around 2 to 3 weeks. One of the cochins was a little lethargic and is around the 2 to 3 week mark. And one of them had bloody poop. Could this be cocci? The chicks are all eating and drinking fine. But I noticed while changing the paper towel bedding that there were some blood marks from one of the chicks. After finding no injury I noticed it was in the poo. Any ideas? I don't want to medicate them unless nesessary due to their young age. And I know it's normal at some point to find blood in there poo, just usually not this young...any help is appreciated!
