I gave my peacocks injections last night, because they've been sick. This was their 3rd dose. Shortly after, one of my peacocks trembled around, like a seizure, and he's not acted right since. If he tries to stand up, he does a somersault ... His legs work fine as he lies down and goes in a circle. His neck is to one side or the other, but alert otherwise... We're giving him rooster booster orally with a syringe, as well as feeding him oatmeal with Nutri-Drench to make sure he's getting fluids and nutrition... Any ideas??? The rest of our peacocks are just fine...
