@ KMG - How long do you typically let it sit? Is getting "cold" a concern? Two feedings ago, I left one about an hour before it was gone. With the last one, I left it for awhile and he just put his head down right next to it. It wasn't until I opened up the cage and waggled it a little before he finally struck and ate it.

@ Caitlin - ~10-12 days with some flexibility. You may be on to something though. The current feeders are on the larger side of the acceptable range. Perhaps I should move out the days to ~14 until he puts on some size relative to that bag of feeders.
