Hes 18 weeks old. Been with us for a week. This morning I noticed he's walking like he's drunk. He also has some black spots on his comb (pictures coming soon) My first concern is mareks. I've separated him from the flock. He's eating and drinking like normal. He's also lost energy. He lets me pick him up and he used to fight. I'm hoping maybe he got beat up on by an older hen or our other roo? Flick is 20 hens and too Roos, the other of which is 6 months old. Most of the hens are over a year.
