I was told after the 1st week, pick up the food at night. Only let them feed for 12 hrs. I notice they eat just as much in 24 hrs as they do in 12 hrs. Only when I put the food down in the AM they go cazy and they gorge themselfs. I notice during the day they are not always eating. When they get older should I pick the food now it just does not seem to make sense.
