I hang a head of cabbage in my chicken run to keep them busy. Can you do the same for coturnix? I would probably put it in a suet bird feeder for them to pick at. Maybe it doesn't matter for quail as far as bullying. I hope this won't be considered a ridiculous question I just see quail running back and forth in cages on all the videos and can't help but wonder if this wouldn't help. It could be any type of green such as kale or what have you. Just asking! Thanks
