Lonely Rooster?

[SevenSea]

I bought 4 dyed chicks 5 months ago and raised them since then in my apartment balcony quite well. Everyone is OK, there is one chick ( little rooster) has problem. He is small in size, but doesn't look thin, runs away from other three (now) big roosters, doesn't move much compared to other birds, always sits in a corner wherever he is. I used to take them in a field owned by us for 1 hour everyday, it didn't move much while other birds used to run around the field. Strange thing is: that little rooster was the biggest when I got 4 chicks, that little bird was the most active, used to jump a lot, now it can't even jump on a bucket of sand.

Every bird is completely white, seems like white leghorns, I don't feel there is one from different breed. How can I make the bird act normal since other roosters have become adult and aggressive. If you have any queries, please ask on comment section.

Sounds like he may be sick.
Does he get enough feed with the other males around?
