bad news, need help!

hey all
My Bearded dragon is at my dads house for bout 6 mounts now
shes like a foot long and bout 1.5 years old and he has been feeding her salad and the large crickets one a week salad every day
she has gone off feeding for almost a week now, my dad has feed her corn with his salad cuz he thought it was ok for like 2 days until i told him to stop... do u guys think thats the problem??

Corn wont kill her but yet make her feel ill. give her a few more days to ride it out and expect some nasty poop. if it gets worse take her in and may have to pump and or some Meds to sooth the stomach.

yep i thought so
thx for the help
she was only on corn for 2 days then i took it off as fast as posible
