I have a 1.5 yr old Black Sexlink that has been ill for about 4 months now. Lethargic, pale comb, fluffed up and sits on the roost all day, eats and drinks very little, runny stool. I have tried everything to make her better and she has given up. She doesn't even try to move when she is getting pecked. I have decided it is time to put her down and have called around to get a necropsy done. I was able to locate a college that will euthanize her and do a full necropsy for $150. Being that I have 50 birds here, chickens, ducks and guineas, I feel that it is necessary to get it done and possibly get some answers as to what made her so sick. I also feel that I need to know in case I have to treat everyone. No one else has shown any symptoms of being ill. My husband thinks that I am crazy for wanting to spend $150, but I see it as a preventative measure in that I could lose everyone. Please weigh in on your opionion as I would need to bring her to the school today. Thanks
