We are getting 10 black jersey giants from TSC tomorrow. We are drawing up plans for the coop and run. I used the chicken math and came up with a coop size of 7' by 6' and a run of 7' by 17'. That seems awfully big for the run. However I don't want them to suffer because of overcrowding. We were wanting to do a roofed run so they have a nice dry area to be in. We are figuring costs now. I hope it doesn't cost TOO much. We have alot of scrap lumber in the basement but will still need roofing, farm fencing, hardware cloth, windows etc. How big is your coop and run and how many chickens do you have?
