I know there are posts discussing this but I wanted to explain our exact situation and have specific feedback-

We have 7 week old chicks from a local farm store in western Massachusetts. They've been raised inside. We haven't had the heat lamp on for them for a couples weeks as it is generally 65-70° in our home. They (and we) are ready to go outside to their new home. Being spring, there is a large flux in temperature. The lows over the next few days are between 40 and 50. The question is this- will they need supplemental heat sources or are they fine to go directly outside in the brand new, non-drafty coop? Thank you!

Chicks are typically fully feathered at 4 to 5 weeks of age. When they are fully feathered they should be able to handle those temperatures easily. A non-drafty coop means they will not get hit with a cold wind.

I've had chicks 5-1/2 weeks old go through temperatures in the mid 20's Fahrenheit with no supplemental heat. I understand yours have not been acclimated to colder temperatures. At 7 weeks that will not matter.

If you are uncomfortable you can supply supplemental heat as long as you are careful to not start a fire. It will not hurt them as long as they don't get too hot. But that is for your benefit. The chicks will be OK.
 
Something that we do is check their feet temp. If their feet are cold, we add the light, but remove it as much as possible. We slowly transition ours over a course of a few weeks. Transitioning from a constant heat source to nothing. If you are going to place something in a coop, they have heat plates instead of lamps. Lamps can easily start a fire.
