I didn't really examine it too closely, it was unfortunately more of a post cleaning afterthought, as that seems to be all ive had time for recently. If I get another, I'll look. The breeder I got them from saaaaaaid they were a year old, but he was more of a middle man breeder, he had purchased them from another breeder and was selling them at a reptile show in tampa.
They look full sized though, and I'm not sure how rapidly they reach full size because somehow in all this time, I've never had a baby collared.
I'm thinking of starting to feed them with tongs, or in a separate, empty container. Maybe tongs just for the ease of it. 
They're ravenous, so with tongs I suppose I'll get a much better idea of how much they're really eating. Hurley, the male, seems to eat twice as much as Roswell, the female.
Any bad expenience with tongs?

>>So good to hear from you and also your 2 lizard kids are doign well. As far as the light colored feces, does sound like sand.

>> Does it appear to look sandy or gravely/rough ?? How old are they now? If real young maybe paper towels would be better for a while. Sometimes when I have younger collareds I just take a handful of sand and scatter it, kind of leaving the bottom glass showing through everywhere, and leave it like that until they learn to catch their pray without the sand.

>>It may not LOOK as nice , but they are safe, learn to target and grab the bugs without a mouthful of sand. Then later add more sand.
