DawnSuiter, your chicks are beautiful. They really are tougher than we give them credit for.
Hi Season and welcome to BYC!
Do your chicks look about as feathered out as DawnSuiters are? If so, they're more than ready for the (draft-free) coop. With nighttime temps. in the 30s at night, you might want to continue to offer a heat source at night for a couple more weeks. It's always a good idea to doubly secure a heat lamp used in the coop. Example, hang it with a chain and then secure it with zip ties or other binder.
Keep them in the coop only for about a week, then on nice days let them have access to their run.
In the future, you might want to start your own thread to ask a new question. That way your question isn't lost at the bottom of someone else's thread.
Good luck and stick around! You'll love it here at BYC!
ETA: If you don't know how to start a new thread, it can seem a little tricky, just PM me and I'll be glad to help you out.
