Hello Robyn 13572;
Your colonies will need protein as well as heat in order to grow. I wrote about the things I fed one of my colonies here: Results From Two Feeding Experiments by RPT - General Ant Keeping - Ants & Myrmecology Forum (formiculture.com). My Camponotus pennsylvanicus founding colonies aren't really that fond of mealworms, so I feed them cricket pieces and flies, not fruit flies, just regular house, greenbottle and bluebottle flies. I also feed them cooked chicken and liver, raw pork and cooked egg yolk. Might as well get them used to eating it right from the start. Fewer insects means less trash! I feed founding colonies every other day and then every six days out of seven as the colony gets bigger. My ants accept a wide variety of foods and I'm sure the diversity is good for their health.
Supply them with sugar/water in a l:3 (some say 1:4) ratio, even if it's just on a small cotton ball or piece of sponge. Honey as a food for ants just seems to me to be too full of potential risks like pesticides and fermentation/spoilage in the feeder. I just use sugar. They also need fresh drinking water at all times. A heated colony will dry more quickly than a cooler one, so they may need additional hydration.
Mine prefer a nest on the dry side.
Good luck with them.

My father always said I had ants in my pants.
