Hello I've been reading all the posts and learning so much. Today we completed our first coop and run. I still have to find some chickens around here and hope to do so soon. I'm hoping someone might know where to buy healthy chickens in the Portland Oregon area. I also was wondering if I have sand and straw in my coop, can I dump that in my garden for next year? I know chicken droppings are good but what about the straw and sand that is sure to be picked up with it? Thanks for the help.
