Welcome to the thread Wright...
Since you are incubating now, the September chicks will be fully feathered out before winter hits. I have a broody who just hatched out chicks 2 days ago. I have another who was on some eggs from the neighbor. They were not fertile, so going to give her some new ones... or break her... Hmmm... I also got chicks in January, and put them out in a coop towards the end of February, with a small heat lamp till the end of March. Well anyway, I guess what I am saying is, the chicks you are incubating now, should be just fine come winter. They'll be near full grown by then.
If I am saying anything not right here, don't worry, I'll be corrected.
