I've been feeding bml for a while now. Once upon a time when I didn't know any better I gave them different fruits n veg , and modified things to get them to eat it etc... I also wanted to give them variety.
What I learned is this, variety isn't as important as a consistent balanced diet. Even when I was offering a veryyyyyyyyy wide range of fruits n veg for variety, I always came back to the fruits and veg listed for bml because that is what my gliders eat the best. They showed me they really don't require variety and don't eat variety as well. I could seriously give my glider bml, watermelon, and mixed veg every day for 2 weeks and they would eat it just fine.
However, I also learned that I can give variety by offering the allowed fruits and veg in different ways. Example menu for my 4 cages ...
Sund Bml, mixed veg, watermelon
Mon Bml, peas, grapes
Tues Bml, corn, cherries
Weds Bml, carrots, apples
Thurs Bml, mixed veg, cantaloupe
Frid Bml, peas and carrots, honeydew
Sat Bml, green beans and peas, blueberries
Just alternate what your allowed to use and mix it up. This way they are getting variety and the diet remains balanced. I don't do this all the time, I usually give watermelon a 3 or 4 nights a week and mixed veg a lot and they pick out what they want sometimes its more peas some times its more beans etc...
This diet takes all the guess work out of it for you, it's really stupid simple if you follow the recipe exactly and follow feeding instructions
