Variety & Staple foods
What is a staple food?
There seems to be some confusion on what "staple" really means in terms of dragon health and overall nutrition.
Staple doesn't mean picking out one live food and one non-live food, like super worms and collard greens, for instance, and feeding just collard greens and super worms for six months on end, every day, without change. That's no where near balanced nutrition.
A staple food is a food that you can rely on, but not solely. No dragon should only be eating one or two foods constantly. Staple foods - like butter worms, super worms, dubia, meal worms, etc. and collard greens, turnip greens, and other types of greens and veggies that are considered "staples" should all be part of a rotation of foods, mixed along with foods that are given once in a while, like wax worms or horn worms, or certain veggies.
Yes, dubia are great for dragons and so are collard greens but this constant notion of it being somehow "okay" to feed a dragon only dubia and collars every single day for several months on end is insane. All dragons thrive on variety.
What does variety really mean?
Variety means making a base of greens and adding different things to it. Using your collard greens or turnip greens or whatever greens as a base mix and then adding various things like squash one week or however often, and maybe something like cucumbers (peel off), or bell peppers the following week.
Variety is feeding a wide mix of live foods so the dragon isn't getting the same thing constantly, as discussed above. By using actual variety for all ages, you're giving your dragon constantly changing levels of protein percentages, fat percentage, various vitamin levels, etc. for more well-balanced nutrition. This is in addition to the calcium, multivitamins, and whatever else you're using, like bee pollen, probiotics, and so forth.
