My first thought is that waste amino acids in the droppings will overwhelmingly be the ones their diet already provides in excess - which is why they end up wasted in the first place. Not all protein is the same, and some amino acids aren't interchangeable. Those are the ones whose inclusion in the diet are most critical. I'd like to see the rest of the study results, not just the top line summary.
I think our instinctive disgust is a sense that should be attended to. It has evolved to protect us from harm. Quail don't naturally source their protein from other birds' waste. It would be natural if they fed chicken waste to dung beetles, and then fed the dung beetles to the quail. Skipping the intermediary is a very bad idea imo.Only bird litter fed to birds instead of mammals. Probably just the ick factor
Dung beetle farms. Great idea!
well, except that I don't know if there is a type of dung beetle that specializes in chicken poop
