2x lazy gardener - Chicks & adults have constant FF through the day but any left overs are removed at the end of the day. I do not leave feed in their enclosure at night, for the very reason of rodents, roaches & bugs, besides figure they're sleeping. The 1/8C Scratch I toss at close up (4:30 - 5pm) keeps them busy & know they'll clean it up before dark.
