I received a 13-month old hen tonight that was given to me because her owner thought she stopped laying because she is acting like a roo towards the other hens. I have a roo, so we thought we'd try to remind her that she's a hen...well, I just noticed that she has some very light yellow pasty poo with small blood streaks in it. I just looked at it under the microscope, and comparing it to my parasitology books, there's a few suspicious-looking things, but I can't make a diagnosis. She's eating & drinking fine. Any ideas? I am concerned about taking her home tonight and putting her with my flock, but don't really have any other options... THANKS!!
