yesterday I posted a message about a wounded chick (5 weeks old). He (not sure if it's a roo) has survived the night in a separate cage and the neosporin has prevented further trouble. There is now dark caked blood over his head but no red fresh blood. He is behaving normal, active and eats. I know that chickens will peck at fresh blood to the point of killing. Can I turn him out with his siblings, separate from the layer hens? I really need advice soon before they don't recognize each other and I have to re-introduce him.
