I am from Evans GA. They seem very happy, we have seven babies and have offered nectar and water so far. Here is a pic as of last night.
Looks like they all have very full belly.
As to feeding, once the first brood (they’re called nanitics) hatch, you should provide more than sugar water. That should be good enough for the workers but the queen needs protein to make eggs. Camponotus species are carnivores so in addition to nectar (3:1 water:sugar mixture) you should provide feeder insects. Crickets, fruit flies, mealworms, each colony seems to have their preferences. Check the care sheets under General Ant Keeping here on the forum for more information. Feed regularly but avoid leaving remains in the tube as that can promote mold and sicken your colony. You can catch your own feeder insects but avoid it if you live where pesticides have been used on the lawn. A humane way to prepare feeder insects is to freeze them. Keep your supply frozen as it preserves their nutrients, kills some parasites, and keeps them from decaying. Before feeding them to your colony, dip them in hot water for a few seconds (also a preventative against introducing parasites to your colony). Good luck with them!
