We just got our first chicks, 6 total, and they're currently in a 50gal storage container in our basement. We have a heating lamp on one side and noticed that they wont leave the area under the heat lamp, even to eat or drink (we pushed everything closer to the lamp as soon as we noticed and they chowed down right away) and if we pick the chicks up they start shivering as soon as we bring them out from under the heat lamp. Should we put another heat lamp at the opposite end of the container until they get bigger or is just the single one fine for now?
