Hello
i have a 1 year old camponotus chromaiodes colony in a fortress THA formacerium. The past month one morning I woke up and noticed the entire colony including the queen are in the outworld with eggs and brood. I figured maybe the nest was dry and added more water to water tower. After that they moved back in. Over the past few days I noticed they keep bringing the brood to the outworld. And they take it back in the nest. This morning I noticed the entire colony with queen and brood are at the outworld again. The nest is not dry or anything. I will mention the one thing that has changed the past month is I added a heating cable.
