I have 9 three day old chicks in a big box, I brought them home yesterday from the feedstore. They have a heat lamp and plenty of space to get away from it. They seem to spend quite a lot of time piling up together, but they're not under the light. I thought huddling was a sign of being too cold, but wouldn't they be directly under the light where it's warmest if that was the case? Do they just like to sleep in piles?
