Worried

I kinda remeber leave four crickets in her enclosure earlier but only found three just now. Does this look like a hungry frog?

Nope, a hungry frog would be staring at the crickets, unless it's staring at one not in the picture. I realise you want to take them out after a few hours, but leave them overnight. By the way, if you are removing them in a few hours, does this mean your currently feeding during day time? If you are, leave them in overnight because horned frogs become active then, it might be trying to sleep.
I leave 3 crickets per night in with each of my babies, every morning I take 1-2 out.
