Man, some of them just seem to like to beak dig.The front board is 4" tall so the depth is 3 1/4".
I have one or two that peck and peck and peck at where the feed comes out of tube and fill the deep dish up. Wonders if it's their instinctual need to eat off the ground, so they try to get the feed down there?<shrugs> Anyway, when that happens I stop filling the funnel until they empty the deep dish, I usually only put out what they will eat in ~24 hours, but that can vary. Not really problem here as I feed daily, but for folks who want more than a days feed out it certainly could be wasteful.
