How long do the Henry's blocks stay good to eat in the cage once placed with the flyers? My flyer will "squirrel" away some blocks and eat later. Is there a need for me to remove any of them at a point in time? Thanks.

Hello John, Henry's blocks won't "go bad" in the cage, but they will dry out. With a flyer, it's best to cut the block into smaller pieces so he'll tend to eat the whole piece right away instead of stashing it. Cuts down on waste too! Please call us if you still have questions. Leigh

I would just leave him in for a day because you don't want it to mold
