Build a big WALK in coop before you order sexed chicks from a major hatchery. Chicken math is real, brooding them indoors gets nasty fast and chicken disease is to be avoided at all costs.
Welcome. Agree with @Kiki about the space - space in a coop and runs solves many potential issues, bullying, boredom, illness to name a few. Make sure your run is secure with 1/2 inch hardware cloth - sides, top and make an apron - it is when you extend your hardware cloth from the bottom along the ground out about 2-feet - for digging predators.
