I can honestly say that I don't have that problem with any CB babies as long as they get at least 13 hours of "daylight" and are kept at regular summer temps. In other words, they don't know it's fall so they don't go off food. Some of my adults did go off food for few weeks but I think that's because things cooled off and daylight coming through the window got shorter. I just increased the day by a couple of hours and increased the temperature a bit and they soon started eating again.
