At the rate these babies are eating they should weigh 20 pounds each soon! I'm using a 1-quart jar feeder and filling it 2 or 3 times a day. We have had 6 of them a week and 2 days, and the other six since this past Saturday evening, so they aren't old at all. I think they are all eating their fair share for sure! Not much of it appears to be getting wasted either. I think tomorrow will see me picking up another bag of food for them at TSC.
