I see where you’re coming from. Plant proteins are cheap, that’s why they’re used. The thing is, chickens naturally chase bugs, eat mice and frogs, lizards, even baby birds that happen to be in the wrong place at the wrong time. Feed is meant to provide the basic needs for the birds to live, but still be cheap enough for the consumer so the manufacturer can make a profit.I mean if you kept a chicken in an enclosed facility like say a large chicken barn, and you fed it Purina Layena crumbles for its whole adult life, the only thing not vegan about it is the oyster shell. And whatever bugs the chicken would stumble across.
One could argue that most chickens in the whole country are probably vegetarian, or close to it. Am I wrong?

I'm not even touching on this specific scenario, nor promoting anything. Just a label reader.
A lot of research is being done around using bugs in feed, particularly BSFL. The reason is that the grubs can and will eat anything that’s decaying whether it’s meat or produce, which can help with waste management, plus they are nutritionally better for birds than plant proteins and more like what they would eat in the wild.
