My DH built me a coop for Christmas. It is a 10 x 12. I still need to get it painted and all. In the meantime, I need to figure out what I am going to put in this lovely coop. I want a variety How old should they be to start out with I want them to free range -- how will they know to go into the coop at night? How many should I get. Currently, I have three game hens, one game/barred rock cross hen, and Dominecker roo. They all free range and use the trees for roost -- will they eventually go into the coop? they are pretty wild and I cannot get my hands on them. any suggestions are very much appreciated. Oh, and where to buy from????
