I have 4 silkie hens and one silkie roo. One of my hens and my roo both became sick at the same time with the same symptoms. But my other hens are perfectly fine. I took them to the vet and had blood tests done. They found signs of a possible viral or fungal infection. They gave my two weeks worth of meds. In the first week they made improvements. By the second round my roo took a turn for the worst. He's still hanging on but I don't know for how long. My hen got better but she has very poor balance still. She's walking a little weird and trips and falls easily. She isn't showing signs of pain and seems perfectly happy. She is scratching around, jumping on things, comes running when I have treats and even picks fights with one of the other hens that she has never liked. My roo has the same problem with his balance and walk, too. But he also still has other symptoms and isn't active at all. The vet just doesn't know too much about chickens and I have yet to find one that does. What could be going on? Will my hen get better? Could it be from a stroke? I'm so lost and I just want to get them better. Please help! Also, they are both about 2 1/2 years old. I don't know if they ever had vaccines, and they tested negative for worms/parasites.
