im going to be getting my first chicks in about 2 weeks. i've never had chicks before, and i need some advice on chicken coops. thanks (FYI, im getting 6 chicks. 2 wyandottes, 2 buff orpington, and 2 americaunas) how big should the coop be? how many laying nest will i need? im not sure if each of the six hens will need one or if they can share. thanks!
