Hello and Welcome To BYC! You can leave newly hatched chicks in the incubator for a couple of days, I like to get them out about every 24 hours, other people go longer. Here is a really nice article on hatching eggs you might like. https://www.backyardchickens.com/a/hatching-eggs-101 You might like to check out the BYC Learning Center, lots of good articles on all aspects of chicken keeping you'll find helpful. https://www.backyardchickens.com/atype/1/Learning_Center Chicks are generally pretty much feathered at six weeks and don't need extra heat unless it is really cold. So when you can take chicks out of the brooder into the coop depends on the temperature, if you can give them the temperature they need in the coop ... if it is warm where you are, especially at night, or you can put a heat lamp etc for them in the coop, you can put them out sooner.
Thanks for all info these are game chicks got perfect pair mom and pop so anxious how babies going to look. Got 19 eggs in incubator one hatched and one with its head out trying to come on out
Kelsie has given you some great advise. I like to get them out by 24 hours or earlier if I can. If anything is pipping and it has been 24 hours and chicks need out, I will mist the eggs well to help them from drying out.
Good luck with your hatch and welcome to our flock!
