So after a lot of research I'm starting to think my white Leghorn has LL. She is 5.5 months old. If anyone has had experience, I would really appreciate some feedback. She started acting strange on Sunday. Lethargic, sitting a lot, and had not laid for 4-5 days then Monday I noticed she was panting and took her to the vet. $100 later there was not much of a diagnosis, other than the obvious. Vet sent us home with a broad spec antibiotic thAt we should administer 2x for 10 days. This is the end of day 5 and my poor henny is not showing improvement. She's eating very little so she has gotten very skinny. Very lethargic, has greenish white watery poop. Comb is all flopped over and pale. So sad. Poor girl. She pants constantly as well. She's been separated from the flock since Monday. None of my other 4 hens show any symptoms whatsoever (all 4 are diff breeds) so this is why I think she may have LL that was geneticAlly passed from her mom. I would think that after 5 days of antibiotics, if it was something curable, she would have improved by now. Not sure if I should wait out the 10 days if she is just suffering. I am aware that the only way to know for sure is a necropsy, but I just don't have the finances for that. Our vet treats chickens as "exotic" animals, so cost for a visit is higher than for a dog. So ridiculous, chickens are the most domestic animals on earth! EXOTIC? Also, I've never culled a chicken or anything else. So i have no idea what to do if she doesn't pull through or just die on her own. Any suggestions.? Can I drop her off at the Humane society?
