hi ive had my 12 month old beardie 3 month now and he was doing fantastic my local reptile shope delivers my live food and said i needed to feed him bigger crickets.ive now changed to the bigger ones but pumpkin wont eat them if i put the tub near him he backs away and goes behind his rock.he still eats his locust and veggies with vigour.ive also noticed today that when he is out of his viv he tries to get the mcro crickets that i have for my baby bierdie. should i go back to the smaller crickets for him ??? ( just to clarify he was on large silent brown crickets and moved up to extra large )
