My chicks are 2 1/2 weeks old, and i have 16. The are in the coop in a large dog cage and the heat lamp in hanging from the ceiling (held by 2 different locations). We would like to just let them in the coop without the cage but i am not sure how to deal with the heat lamp. We do have a light fixture in the coop for winter lighting, could i put a heat light bulb in there? Im not sure that would give them enough heat. Any thoughts? Oh yes the coop is pretador safe, and ventalated also.
