I have a 1 year old male pekin and he's acting totally lethargic. Started about 3 days ago. He just seemed weak. Now we have separated him from his brother and he's in a "rehab" pin. He's getting worse. Now he won't stand or anything. Hasn't eaten or drank anything. His eye was crusted over yesterday and I got him all cleaned up. But he can't quack or anything. He opens his mouth but no sound comes out. He doesn't have enough energy to stand. He just lays there when he normally runs from us. I'm not sure he's going to make it much longer. I don't know what I can do to help him. Please help!!!
