Hello all!! Of course, just like most of you here, I have become addicted!! I am thinking of building a bigger coop but haven;t the slightest clue where to start..this is where you all will come in... I need to know what the best materials for building a coop are? I need something that will be inexpensive , but will also keep them warm in the winter, cool in the summer. Would particle board work??? I would want to built one that could accomodate 10-12 standard sized chickens. I now have 7 in a 4 1/2 x 6 house...which is a bit small but they have all have plenty of room to roost, nest and scratch around on the floor. They have a nice 16 x 10 run, but are rarely in in, they free range most of the day. How big would they need and what do you think the cost would be if I was to stick to a strict budget?
