Since I am the retes connected to the boards, I will give this a try. First, no holes in the middle, this is contradictory to th design of the boards. The holes turn the boards into a jungle gym instead of a home and shelter. Also. the spacers to keep the boards apart are suppose to be aprox. the height of the monitors using them. Monitors like tight spaces. Ackies particularly can live and shelter in cracks that are 1/2 their height. I have different boards for different sizes, I also put several size boards to give monitors their own choice. Then I do not stack them strait up, thats a human thing, I have no idea why people think thats nice. I alternate the boards, the first board is on the surface of the ground the second board in 1/2 on that board and 1/2 on the ground. You can do many combinations of this. This makes many many different areas for monitors to pick from. Remember, nothing is stopping you from doing both, for instance, the lower boards alternating and off center and the upper boards with holes and stacked. Now you have tight shelter and a jungle gym. Remember its about allowing to pick places only they know they need.
About diet, you can rely on dusted crickets(vitamins and calicum) to allow ackies to grow up, mature, reproduce and live a long life. But, the addition of other whole food items is absolutely great. I do feel your schedule is silly. there is no need to be so strict. They need food and all but the turkey is good food. The benefit of crickets is, you can throw more then they eat at once and they can eat them, at their leisure. Monitors do not eat once a day or so many times a week, they eat when hungry. At times, several times a day. Your job is to allow that with your monitors, in your set up and conditions. The turkey diet is good to keep in the freezer and use if you run out of whole food items.
Remember, its the results of providing all this and more that predicts how well you are doing. How fast they grow, how large they grow, how much they produce, how long they do it, how long they live after doing the preceding events. Those are what tells you if you did poorly or good or great, not the fact that you put them in the cage. Your job it to use the right tools and guide your animals towards success. As far a I know, there is no one setup that allows all this, not even in nature. In nature, when they out grow an area, they move to a more suitable one. So it is in captivity. F Retes
