I have five chickens and recently one of them started getting sick when she started a heavy molt. She couldn't walk straight and looked drunk while walking. We took her to the vet and they gave her antibiotics in case it was an ear infection and I had found another thread about a chicken with the same symptoms and they were treating her with hypericum in case it was Marek's so I started giving that to my chicken. Currently we have her inside away from the other chickens and she is a whole lot better. She can walk straight now, she holds herself up, and has a lot more energy than before and fights us when giving her her meds. The problem is she is still not eating a lot. It seems like she wants to eat but she either can't or isn't comfortable eating. A few days ago when she first started getting better she started eating a lot but she kept stopping and stretching out her neck and opening her beak almost as if she was choking. Since then she barely eats. She had done it before getting sick but I didn't pay much attention as she did it once and kept eating and didn't do it anymore and seemed otherwise healthy. Now she has lost weight in this past week and barely eats. Could it possibly be Gapeworm? I gave her a dose of Safeguard (Fenbendazole) Equine Dewormer 25 gram Paste 10% incase it is and i'm planning on giving her another dose in ten days. Any advice?
