Generally when mine do this I continue with the same number of feeds but only give them as much as they want. Its normal for them to loose some weight. If you chase him around trying to make him eat, you'll really slow down his progress and likely cause some problems. It can be kind of alarming at times. Especially if they go through a phase where they don't want formula, but they aren't eating much adult food and all they want to do is flap and fly and destroy stuff. You just have to have faith that its a phase. You will eventually notice a lot of crushed pellets and mushed up soft foods and evidence that he's really eating. If he really cuts back on formula, drops a bunch of weight and doesn't start eating, sometime you can adjust the timing of the other feedings so the next one comes earlier. I have noticed a lot of times at this stage, they'll guzzle a little bit of formula and then go right to their adult food when you put them back in their cage. Or if they aren't interested in formula, give his a couple hours with some warm or fresh soft foods and then try the formula again. If he doesn't want it, he doesn't want it. His body will tell him what he needs.
