Good Morning All I added the “in kitchen” to the title because it’s where I have them right now and that may be important information. There are 6 chicks and they are 3 weeks old. I have them in a large Rubbermaid tub with a heat lamp I keep rising so it’s not too hot. My question is - given they are 3 weeks and they are in the kitchen where my temp is about 68-70 do I still need the heat lamp on 24/7? Thanks!
