I live in nj and my chicks are 5 weeks old and it's cold out should I use heat light in coop and should I let them stay 3 more weeks in my basement

After reading all the previous comments, my girls are moving out tonight. Temps for the next two weeks are lows in the 50's. Hurray for chicks and people! Have 3 Phoenix/ISA Browns that wait for me to take them outside to the run every morning. They have been enjoying the afternoons in the run while the temps were in the lower 60's during the day. This past week, they have spent almost all day out there. This morning, as I took one of them outside, I came back down to the basement to find the other two standing on the table by the brooder box waiting their turn (impatiently). The last one tried to follow me out the door to go outside. If it weren't for the hawks I see overhead sometimes, I would have let her. No more squawking and grumbling as they have to go back to the brooder box anymore!
