Even though there are 5-6 different greens suggested for feeding, it doesn't mean you have to feed them all. ? That makes it easier for us, so we can feed what's available. If you're feeding a couple different greens, in my opinion your fine. I switch off every couple weeks, depending on what looks good at the store. Having only 1, as Brandon said, is different from having more dragons. Last trip to the store yielded some nice collards, before that was Mustard which he didn't care much for. His fave is Turnip greens but can't always get them. Being winter, some things are harder to get. If we have a couple warm days, I'll pick a few small tender dandelion leaves from the yard (NO chemicals in yard) to add to his greens, not a fan, also a few tiny leaves of wild mint, also not a fan. Trial and error. But he always has a green with a squash, either summer or zucchini, shredded sweet potato or carrot, sliced snap bean, etc, so he has variety. I do use a tiny bit of vites and calcium powder a couple times a week, he's 2.5 yo and eats well but I feel better for the addition to his food. ?
Sorry about writing a book! LOL!
