Yes, I know the Cheras padang, have been there a few times. The crowd there is ok but some of the people are dodgy characters, so I try to avoid it.
To quote Sam (above) dodgy characters will always be there and to share an encounter with some of them, I was told in no uncertain terms, expletives and all that I should not hang my new or immature putehs next to theirs as it will affect the so called "form" of the birds. Adding salt to the wound, I was to blame when their birds went into french molt the following week. All these took place not in Cheras but in another arena. Any forummers here care to comment ,not on those characters but on whether it is true that young birds should not be placed together with "seasoned" birds during training.
Warmest regards to gentlemen like you out there.
