Greetings
Conrad Schweizerhof,
When a rooster becomes so weak that they are having trouble walking or standing, you know it's serious. You are right to be concerned.
There is more to his condition than lice or mites.
He is pale; I would administer a vitamin supplement with iron in it. Give it to him orally for three days. And as
micstrachan, suggested, you should put electrolytes in the water for few days. Also, give him some, in a syringe, full strength. About 1 mL, will do him some good. These two things should give him a boost.
He also needs meat protein daily, at least a tablespoon a day. If he is not eating feed, offer cooked grains such as brown rice for energy, cooked vegies and diced fruit to raise his blood sugars, which are probably low. Cooked food will digest easily and quickly, and if he has low appetite, the cooked food should entice him to eat more.
If he stops eating entirely, then, you'll have to feed him a slurry of bird meal replacement with a syringe. Or, you can tube feed him if you know how. Hopefully it won't come to this.
A picture of his poops could indicate what is ailing him. I know you looked him over, but check again.
Do a basic exam:
- Check under his feet for cuts, scabs, or sores.
- Check the shape and color of his pupils for any changes.
- Look inside his mouth for any sores or growths.
- Also smell his mouth for anything foul smelling.
- Smell his body too, there may hidden wounds under his feathers, that are infected.
- Check his vent for any caked up feces that could be clogging it.
When a chicken gets thin, it's because they're not eating enough due to infection, have diarrhea, have internal parasites taking their nutrients, or even tumors (but tumors are more common in hens). Most times it is more than one illness that overwhelms the bird. If it is chilly at night where you live, he may have congested lungs. Listen for any gurgling, wheezing or labored breathing when you pick him up.
But, his poop is an important clue, so get a picture and upload it, so the members can see it.
I would also put him in a hospital crate, for at least a day or two, to better monitor his progress, medicate and treat, feed and give the rooster a quiet place to recover. As he starts to feel better, you can give him visits with hens. However, if you have multiple roosters, you will have to treat him in the pen. Because if you remove him, you may not be able to return him, as, the other rosters will attack him.
These are my thoughts on your rooster. Other members will have advice, please consider them too.
God Bless
