i moved my 3 ducks outside at 2 weeks for the same reason. we didnt use a heat lamp but they are housed with 2.5 mo old chicks to help stay warm. the temp has dropped into the low 40's and the birds have been fine outside for 2 weeks now. as long as you have the heat lamp they should be fine.
Some of my baby chicks, outside for the first time. But sooner or later, they need to go outside. If you have more chickens, you will need to introduce them carefully to the big girls (and boys). But before you even start to think about that, it's a good idea to get your chicks used to being outside at all.
