Hi, I m the proud owner of 13 ex batt hybrids that I re homed in two batches (march and August). One of my latest ones has always been a bit poorly, became very ill after a couple of weeks, to the point where I kept her indoors (she didn t move from her box for two weeks) and I was sure I would lose her. After a 5 day treatment of antibiotics she improved but since then she has remained very lethargic, extremely thin (1.3kgs as we speak, she was at 1.1 at her worst) and naps throughout the day. She has had diarrhoea for two months now, it had improved after the antibiotics but not for very long. She seems otherwise quite happy, she s outside part of the day and rushes to get in when I open the door (she sleeps inside at night and comes in to nap once or twice during the day) My vet (not a chicken specialist) has run out of explanations and I m not sure what to do. Could it be Clostridium perfringens? Or some kind of cancer? What disease could last for so long without any signs of improvement? She hasn t laid for the past two months (the only one in the flock not to) Thanks a lot for any help or advice, I am running out of ideas of what to do!
