Thank you! Yeah, the mite sprays seemed sketchy to me, either the ingredients seemed useless or questionable safety wise. Will not use!

Also, I think Coyote gets some of his feathers messed up when he's messing around in the budgies' cage because he's way too big for the width of the cage. So he's always bumping his feathers into stuff as he stumbles around, eating their food and messing with their toys.
