It could they are to big. I have been watching it eat...I see it eat 5 in a row and then it can't swallow the 6th one..could be the 6th one was to big or maybe it's stomach was full..not sure how their digestive system works..but I have been seeing it eating which is good...oh that's cool I'm in queens.. I didn't notice the the location ..did you go to the reptile expo? I haven't been to one but plan on going eventually
