In the picture he looks like a chubby little guy. At that age it is normal to decide he doesn't want to eat. They don't burn calories the way we do. When he feels like he's got enough meat on his bones to live happily, he won't bite off more than he can chew. Drop down to offering every 2 or 3 weeks; he will be OK. I do agree about adding some security though. What is underneath the log hide also... it looks like some kind of pan or something or is it paper under the coco fiber?
