Hi, its my first time raising chicks, i have 19 chicks at the moment. After 10 days i moved them into their new coop with 2 red lights to keep them warm. The chicks are now just over 3 weeks old, 2 of them can get on top of where i have the lights and i seen 1 of them pecking at the wire so I'm worried it will peck through and either hurt itself or cause an electrical fire. So my question, what is the minimum temperatures chick should be at around 3 weeks? I checked the weather forecast and nighttime temperatures will be around 55 Fahrenheit 14 Celsius I would like to leave the light on for longer but if they are pecking the wires its maybe not to safe.
