It is not legal. It is dangerous to the crocs and to people. According to ACES, the fed crocs are seriously unhealthy and will probably die prematurely. Putting a frozen chicken into an animal that cannot regulate its temperature is hugely damaging. And while some may say that the crocs don't mind, a croc recently taken from San Pedro, which had been fed regularly, was found to have been badly abused with many injuries including a bullet hole and a spear hole.
Forestry have been trying to press the police locally to shut down the operation, but as of yet, nothing has been done - despite the fact that the police are well aware that it is an illegal activity and highly dangerous for anyone concerned.
