So, i have tried varios forms of treats for my guineas. As young tykes, they really liked the dried mealworms, and also a corn/BOSS bird seed treat, but lately nothing has really made them noticeably happy anymore. Would there be any harm in offering them a commercial grade suet cake, BOSS and suet in a suet cake holder on a chain in their coop? Or any other suet cake from the local feed store? Thank you!
