Bleh. I would think not. Get a fecal sample done on both of them and see what they have. They may both have a belly full of worms... Ick.
About the patty baby not eating, I would give him another day or two to settle in. Are they separated? Maybe he is stressed by the other sibling and doesn't want to eat. Try covering the sides of the tank with some dark construction paper. Disabling the crickets(taking off back legs) will help too.
Hope that helps a bit.
