Hi and welcome to BYC from NY State!
Glad you joined us here.
Your 7 week olds are probably just fine with your temps. Try putting a see through divider in your coop and/or run so that the 3 month olds can get used to them and the little ones stay safe. After a while you'll be able to remove it and they'll work out their pecking order.
