Converting Shed to Coop, is this the right way?

I have never raised chickens before but I have been studying up and I have an idea of what I need to do to convert our 10'x11' metal shed (with a cement floor) into a coop. I would greatly appreciate any input to tell me what I don't need, what I am forgetting and what could be done better. I plan on raising between 6 and 12 birds in here.



This is the front of the shed and it faces south, I plan on cutting 2 to 4 windows out of the front (two in the doors and one on each side) and putting wood framed pexi glass windows in that will be hinged to open and have some sort of secure closures, and will have hardware cloth on the insides. I was also thinking I might need to cut 2 vent holes in the top part above the door and covering them with 1/2" hardware cloth as well. I am not sure how big they should be though.



This is the inside of the shed, in here I plan on putting a thin insulation in and covering it with ply wood nailed to the studs. I was going to make 3 nest boxes and secure them to the north wall. I then plan on attaching their roosts on the east wall secured with hinges for easy cleaning.



This is the east side where I plan on putting a detachable hoop house run. I will cut the chicken door out of the right side.



This the north side which is sheltered by woods, I plan on cutting out of the gable vent holes with some sort of optional covering and cover the insides with hardware cloth. Again, I am not certain what dimensions these should be.



On the right side of the coop there will be a detachable run (tractor) that I would like to keep the girls in during the day so they can get the benefits of free range chickens without the danger of getting in the very busy street at the front of our house. I would like to make the tractor 3'x 5'x20' hoop house style, probably out of cattle panels covered with chicken wire secured to wood skirting and staked with landscaping stakes. I would put a door in one side to slide open to correspond with the door of the coop. Does the tractor need to have nesting boxes in it? I know I will need to put water in the tractor, but will I also need to put feed in ? Or will the grass be enough until they get put up for the evening?

 

Thanks for all the input so far.

Ok, I confess the chicken tractor idea I haven't completely figured out yet. I love the idea of free range chickens but where I live I would be afraid of them getting hit and into the neighbors yards. We have 3/4 acre so I wanted a way to utilize the various grassy areas as well as the garden area when it is not planted. So my reasoning was to make their run movable so I could place them in a new grassy area each day and return them to the coop at night. I have seen various designs for chicken tractors and wanted one that would be simple to make and give them plenty of room. This chicken tractor was my inspiration for my idea: http://img.photobucket.com/albums/v386/ChevyGirlBeth/Chicken%20Hoop%20House/IMG_4060.jpg. Only I would make it lower to the ground (3-4 ft tall) and put wheels on one end that can be removed like in this photo:http://lh5.ggpht.com/_eQ-gLiqGzO0/SacMAQFofUI/AAAAAAAABpY/Abh0eRqXK94/s400/IMG_9972.JPG. In the winter I would just leave it next to the coop. It probably would be a good idea to use 1/2 " hardware cloth instead of chicken wire. I am thinking I may also need to find a way to weight it or stake it down securely to keep out predators. I am also trying to work up an idea to have a little hinged covering over the nests, food and water containers for easy access. I would also need to have them secured to the sides so they would move with the tractor. Boy, I never knew this could be so complicated.

I will try to be careful with cutting the metal, the gables where I would put the vents are wood and the doors where I would put two small window are wood as well so that should be easier. I would also enlist the help of my dad and brother who are more experienced in construction. I was also thinking of framing the windows and chicken door that will be out of the metal with wood to cover any exposed edges.

I still need to figure out how to do the vents in the top, any good ideas?
