OK, I've tried collard, mustard and kale greens. My turtles don't really like it---some nibbling, but unlike romaine lettuce, which they completely devoured. Any tips on getting them to eat the stuff that is most nutritious? Any other greens or fruits that are good for them?
By the way, my birds don't like collard, mustard or kale, either, also preferring romaine. For the same reasons romaine is not good for the turtles, it's not good for the birds, either. Any tips on them would be helpful, too!
