Coop Heating Lamp HELP

[Newbe owner]

Our chicks have been in the coop note for almost 2 weeks and i still turn on the heading lamp for them at night. I live in arizona so our temps at night are in the 50 -60 degree range and during the day it's between 78 and 90 right now. All the girls appear fully feathered (this is my first flock so I'm not quite sure). Do they still need the heading lamp on at night? I have a fan in there during the day (very secured) to help with airflow as we are still finishing up their run. Any advice would be greatly appreciated!!!

if they are fully feathered and it is 50 or 60 at night they will be fine.

They don't need supplemental heat at that those temps.
