I hope you start with a coop, as those chicks grow like weeds! We do have a Coop forum full of beautiful and some very simple coops our members built, and a Learning Center that might also help you!
Welcome, welcome! I don’t know if you’re planning on buying a prefab coop but if you are, they’re always much smaller than they say and pretty wimpy as far as strength wise- you’re so much better off building your own or converting a shed- my duck house is a converted children’s playhouse 6’ x 8’ perfect for 12 Ducks
