Are my flock healthy?

Hi, i have a flock of three roosters and they are 4 month old. One of my chickens stoped chirping and his sound has changed, but he has feather loss, his hackle feathers are also very low. When they fight, his hackle feathers will raise and the skin is visible underneath. He also sometimes open his mouth. The next chicken has also feather loss. He wags his tail often. his butt has some down remaining. His sound has not yet changed and he is the second largest in the flock. The last chicken is the smallest. He has the worst conditions as his tail feathers are still growing and his neck has bare skin. Is they healthy?

Are they maybe having an early molt? Be sure to check for lice and mites.

Are they picking each other's feathers?

What does their poop look like, and what are you feeding them?

They don't look bad to me in the pics, but I'm looking at them on my phone, so they are kinda hard for me to see.

I am sure they won't get lice or mites because we regularly check them for mite and use preventive medicines

Yes, they're pecking each other but not too often. I often see them losing feathers when they are flying or running.

They poop black with white on top. But once they pooped white and watery. Please see my another post on chicken poops watery and white for pictures.
I feed them wheat, fruits and vegetables, boiled and raw rice. We feed them THIS because there are no commercial feeds around.

I see. They may not be getting enough protein. They need protein to make feathers. Can you offer them eggs or meal worms?

You might look up recipes for homemade chicken feed.

If the three roosters are fighting, wouldn;t that result in some feather loss?

Yes my roosters will fight often but not too aggressive to cause feather loss. Just staring at each other and some little jumping.
