We have 6 week old chicks that have been outside about 1 ½ weeks. They were raised in the garage. Our weather has warmed up enough that it has briefly stayed in the 60s the last few nights so I turned off the heat lamp altogether. (Previously it was only on at night.) The 60s will last maybe two more days and then it is going to dip back down to 50. So my question is: do I need to turn the lamp back on for the 50s? They will only have had about 4-5 days to acclimate to the 60s and no heat. I figured they are a little soft after being raised in a toasty garage but they are fully feathered.
