How can i help my boy

[Flockking]

Hello everyone
One of my boys not looking too good and I can't figure out what exactly the problem could be, he's very lean with little to no pale comb and wattle
He is an Isa brown around 5months old, he eats fine..poo's fine and even mounts the girls occasionally though he's the lowest ranking male out of my 5 boys they all get along with little bullying so bullying is not the case
I looked at possible problems like parasites, deworming and even antibiotics but he still remains the same so I have come to listen to advise from experienced chicken parents

Please help my boy

Hello! I would treat him with corid, perhaps coccidiosis?

No bloody poo so far and the entire flock was treated for that last month after it was noticed in my 3 month old birds

Not all coccidia produce bloody poo. Do you have pictures of his poo?

Are you talking about the white and brown bird? It's a pullet, which is why the comb is small, lean looking because I don't think it's an ISA brown, but another breed.

What do you feed them?

The white bird I mean

He mates the hens and have saddle feathers
I feed them all a mixture of grower and layer feed

Hotter months? That poo looks great!

I am 99% sure that the " roo " is not a roo. That looks like a pullet.
