beardie spending time on cold side.

[HLSLeO]

hey guys is it normal for a beardie to spend time on the cold side of his tank?... mine, who is roughly 7 months old has been spending considerable amounts of time laying flat on the cold side... he eats normally, poops normally, and acts normally once i start to hold him and bother him... but when i grab him his belly is pretty cool in temperature...

i have come home to find him laying on the far cool side of the tank a couple times ever since i upgraded his tank to a 40 gallon... once i feed him and he feels full, he then moves over to the hot side of his tank...

-Lights: Repti-Sun 10.0 18inch and a 100W zoomed basking spot lamp.

-i feed him Collard Greens with Butternut Squash all chopped and mixed every morning sprinkled with ExoTerra Calcium D3.

-i feed him for about 10-15 minutes everyday crickets. he can eat as many as 30 - 40 medium sized crickets in one sitting. (6 times a week with the Exo-Terra D3 Powder, and 1 time a week with ZooMed Reptivite Multi Vitamins).

-occasionally i feed him one waxworm as a treat, like maybe one or two waxworms a week...

-his tank temps are 78 degrees on the cool side and 95 degrees on the warm side, with the basking spot anywhere between 100 to 105 degrees...

am i doing everything alright?... or am i doing anything that may provoke this hanging on the cool side behavior... also, his tail is currently peeling, i dunno if this might be somewhat of a cause... he seems to be normal... it's just, i am worried about him not receiving the heat he needs...

any info will be greatly appreciated... THANK YOU!

here is a pic of his setup, i have the ReptiSun mounted inside the tank as many people have recommended to me... the big light dome on the left contains the 100W Basking Lamp and the light dome on the right uses a regular household 60W light bulb and is there for feeding time ONLY, i feed him on the right open less crowded side and use the light as a spot light then turn it off once he is done... as you can see in this pic, he just ate and was pancaking in his basking spot...

and here is my baby himself...
