I have questions about my sick rooster. He has trouble holding his head up and has black spots on his cone. He is still eating, but has lost a lot of weight. And his chest appears to have dissapeared! I tried to post pics but, for some reason, I can't. Email me at email@example.com for pics. Thanks, in advance, for your help. * Can anyone tell me what is wrong with him? * Is it fatal, if untreated? * Will he infect my hens? * Is it dangerous for people to be around him? * Is it okay to eat the eggs?
