i got two beardies from my local pet store yesterday and i got the food and everything...but i dont know how old they are? is there anyway to tell? i know that the pet shop took good care of them they are the best at caring for the animals. so if size can be an indicator let me know because i know that they are healthy ...also the pet shop always gave them crickets but i bought juvenile pellets with freeze dried insects in it. but they wont touch it one wont even look at it and the other only picks out the bugs.. how can i get them to eat the pellets also i really want to make sure that they get a really good full variety diet. thanks for any info you can give.
