night temp

Question
I know the care sheet says the night temp can go as low as 60. My bearded dragon seems to be too cold at night but his thermometers read 71-73. He has been sleeping perched on his water bowl (longways with his body supported by the rim and two legs dangle over each side)- which is kind of cute, but he doesn't seem to want to move from that spot even to warm up in the morning. the result is he won't eat his crickets an hour after lights on. This wouldn't be a problem but I make just enough time for him to have an hour to warm up, then feed him while I make his salad for the day, then I have to leave for work. I don't want him to wake up too early or I would have problems with timing some nights, and wouldn't get the chance to interact with him. I try to have the lights on when it is light outside. He will eat plenty of crickets when i get home from work and he does average about ten a day but i would be more comfortable if he would space it out a bit more, he is only about two months old, five inches long and I worry about him eating to much at once, because I have heard so much about impaction. is he acting normal and am I just paranoid? is his temp and lighting schedule ok? is there anything else you think I should change? oh yeah and I know he doesn't necessrily need a water bowl but he seems to like it, he swims on his own every few days, and like I said he sleeps on the rim...

Answer
 Are your thermometers the digital with a probe?  Stick-ons can be off by 20 degrees either way.  If he's a baby, he may want it a tad warmer.
 Sleeping on the rim of thw water bowl is ok, just empty the bowl of water before lights out, sleeping babies can drown or get too cold if he slips into the water.
 As long as he gets 14 hours lights on during the summer, you can arrange it however you like within reason.  If there is a window, he's going to go to sleep anyway.
Winter it would be 10 hours on and spring and fall is 12/12.
