Hi, ya you want to take the baby crickets out. They will be hungry and if they don't have anything to eat they will more then likely eventually bite your frog. I would either feed with forceps or put the crickets in and watch to make sure he eats them. my guys don't really bother with crickets anymore but when they did I never left them in there for more then hour. If there was some left I would catch them and give him the rest by tongs and if he didn't want it obviously he weren't hungry anymore and I would just take it out. You may also want to change out his substrate in case theres more eggs in there.
