I live in Florida. Our daytime temps have been running in the mid-to-high 70s, a bit warmer in the garage where my birds live. Nighttime temps are in the mid-to-high 60s. They're 5 weeks old now and I've still had the heat lamp going. Do they still need the lamp, or can I turn it off? Should I leave it on at night but turn it off in the daytime? I don't know what their behavior is like these days because I'm not out there All The Time like I was then they were tiny fuzzbutts, now I'm only out there a couple times a day to clean the pen and check food and water, and half the time I go out there and SOMEbird has escaped the pen (I seriously need to just give up on the lid!) and is walking around the garage.
