Yea, I have the 12x12 concrete slab, and most of that area of the yard is all over grown with weeds, so my plan is to cut them all down real nice, and let the chickens help me keep them down! I want to start with 3-5 just to get the hang of it, This will be a nice home project for my 7 year old son and I to do together (yea yea i know i'll end up doing 99.9% of the work

) maybe next spring we'll add to our flock, i'd like to eventually find a happy medium between supplying all the elderly people at our church with free eggs, and a decent but not overly tiresome amount of work, so i think maybe a max of 12-16 birds at some point?
