darkened comb on my rooster

[lots-ofchickens]

My rooster, he is close to one now. He was acting fine a few days ago when his comb became a dark red-purple color. Today he has become lethargic and is not eating or drinking. I don’t know if this is something I can fix.

I don’t know but good luck with him.

A dark comb can be from a heart ailment or breathing problems causing a lack of oxygen. Has he been gasping for air? Can you get some Poultry NutriDrench and give him 2-3 ml slowly by beak, and offer water up to his beak? Has he passed any droppings today, and can you describe those? Sorry that he is acting poorly. His comb does not look that purple in the photos.
