I would disagree with this. Though it's not always best, it can sometimes help get difficult feeders to feed by putting them in a small container. In a large area, food can get passed over or unnoticed, especially by flighty individuals.
I start my hatchling hondurans by placing them in an 8 oz. deli with a frozen thawed fuzzy the very day they hatch. I've had 100% success by doing so. Once they take their first few meals, they are usually problem free.
