My 4 chicks are a week old now and I feed them 24/7 starter feed and water and they are doing fine. My only problem is that I have no lamp above 60 watt for heat so I decided to leave it off. My chicks seem healthy but are they really? They like to cuddle at a corner and sleep together. They are currently located in my garage, it is quite hot there because outside it is normally 25-30 celcius, so it should be hotter in the garage. Should I continue doing this or get a heat lamp even though my dad doesn't like it because it waste energy and fire hazard. P.S- If I continue without a lamp are they gonna have any defects or disease later on?
