Welcome to BYC.
Domiqueās are quit big. So the space is really limited for 5 chickens. I would start to build a safe and roofed / sheltered run to the coop. And leave the chicken/coop door to this run open in the night. This way the chickens can go outside at sunrise. And have enough space in nasty weather.
Use 1/2ā hardware cloth, second hand windows and good roofing to keep predators and nasty winds outside. And let fresh air and the sun come in.
Make a larger run , a pen or free range during the day. Depending on the risk you take free ranging or an open pen (hawks).
And most of all, enjoy youāre chickens.
