Yes in a word, dead birds need to be incinerated and the guano transfered to landfill - both need waste transfer notes. Whilst it needs to be done correctly there's nothing to stop you doing it without training. As we stand there is no recognised standard for the training and the authorities don't ever seem to insist on any just a ms and ra. The correct disposal of biohazard as required by the tree huggers is also cattle poo because the fire brigade just hose any spills into storm runs or roadside streams - have you ever seen them with a spill kit on their hands and knees? The sooner they make everybody do it by the book, regulate the training and licence the contractors the sooner we came earn the correct money for the task and kiss goodbye to the cowboys. Do I think this will happen ? nope just like they can't regulate the merchant bankers loosing billions
