Farming soy beans also produces waste and stuff still spoils. Turning that into consumable biomass efficiently via insects or other crustaceans is still a viable option. Especially since their droppings make great fertiliser. Including that in a food production cycle is not the worst idea.
They probably can’t see colour very well though. They may have more receptors but they can’t mix those as well as humans so it’s a bit like looking at an 8 bit game with some new colours. Also the resolution of their eyes is abysmal. Birds have one receptor more (UV) and really sharp vision. That’s where it’s at imo.
