I have a 9 month old Wyandotte chicken. She's been perfectly healthy until about 6 weeks ago. She started with diarrhea and seemed very droopy. I have some medical experience so I immediately separated her from the flock, did a rectal exam, (thinking egg bound) and gave calcium by mouth with electrolytes in the water plus treated her with valbazen in case it was worms. She stayed in my laundry room for 2 days and after all the meds and special treatment, she perked up and was sent back outside. 3 weeks later she had another case of this that lasted for 3 days... Similar treatment (I've tried sulmet, valbazen, tylan injections, probiotics, oral vitamins and electrolytes). She got better a second time and was sent back out. Now this is the third time she's been sick since December 1st. But this time she doesn't seem to be improving. She has no energy and even uses her wings to balance herself when she stands. And she is always sleeping. She has awful green diarrhea as well that comes and goes. I've also noticed she is incredibly thin. Her keel has no meat on it at all. She eats and drinks a ton... But no weight gain. I'm at a complete loss as to what this could be. None of the other birds have any similar symptoms. I have an appointment with the vet on Friday but I'm worried she might not make it until then. Has anyone ever dealt with a similar problem?? Suggestions, thoughts, anything would help. Please. She's my favorite bird. Thanks in advance for replies.
