Over the last 2 days I have been integrating my March 25th Hatched chicks into the coop. They have had visual contact with the older birds for 2 weeks, then I moved them in the day before yesterday. This morning, everyone looks normal, but my little sussex pullet is pooping pure blood. No other substance in the poop, just straight blood. She is eating and drinking. She is not droopy, but her tail is down. She is alert, walking around. I separated her from the other birds, but she is wanting to go back...vigorously. No lethargic behavior. Bright eyes. No one has pooped blood before, there has been no signs of illness in any of these birds until now. All the others are running around, pecking, scratching, eating. She is doing the same thing, only when she pooped on her perch there was a large amount of blood, and once again this morning she pooped and it was pure blood again. Can cocci do this? No other symptoms? Could she have been injured internally during a fluster with the older girls? There are no wounds around her vent that I can see. I need a list of things that can help this. Its $200 to be seen by a vet here and the nearest is 400 kilometers away. Many drugs easily available in the US are banned here or cannot be found. Anything containing "zole" in the name is prohibited from being sold here. Its unobtainable. I know that sulfamethoxazole could help, but again, banned substance. I keep a clean coop! How could this happen?! None of my birds have ever had this before!!
