I highly recommend starting out right, get it all set up well in advance of the chicks arriving, wait till it's not freezing outside and when you get the chicks get them straight out to the coop, skip the indoor brooding part, I find that is where a lot of issues start. a mother heating pad set up is the best brooder, you can do a search to find the thread with all the details. they really do benefit from lots of fresh outside air, but buffeted from draft. the only time I brood inside is for our kids, it's definitely not necessary for the chicks, as long as they have a heat source to go to, they manage to regulate their temperature quite well, running out and eating and drinking and frolicking as desired.
As for the coop, get a metal can for the food, frame out the coop and apply hardware cloth, NOT poultry netting. keeping out the vermin cuts down on disease and predation. make a covered run, envelope the coop and run with hardware cloth, even on the floor if you can, mending the seams every 3-4" with thick black zip ties for anywhere they will be under ground and using fencing staples/U-nails every 3-4" for the above ground part where it gets attached to the posts. I place the posts at about 43-44" centers so you can overlap at the seams a couple of inches, the hardware cloth/fencing comes in 48" rolls, get the the thicker gauge with 1"x1/2" spacing. you can use a 3" long screw and a washer at an angle every three feet or so on each side/post to get the fencing taught, then nail it down with the U-nails/fencing staples, then remove the screws and move them another several feet and repeat. it takes considerable effort to do the hardware cloth right but it is the single most valuable place to spend your money and time to avoid future headaches. the door way framing and door should not have any more than a half inch gap, this is the size of an adult female rat's head, if you can keep them out, you will avoid the problems that come with a rat population explosion. if you build to keep rats out, you can keep everything else out. for the floor, you can dig down about 8" before laying the hardware cloth, then once it's placed and mended, cover it back up with dirt, this will be the base for your hens litter. look up the deep litter method, I highly recommend it. no need to be constantly mucking out the coop, the aim is to create a good micro biome that is aerobic, doesn't smell or harbor disease. over cleanliness can actually lead to unbalanced micro-biology and increase the need for antibiotics. after you have the whole coop framed and enveloped in hardware cloth, I recommend putting a roof on top, chickens do not benefit from rain, it only stands to make their run a pig stye with lots of the wrong microbes.
if you start out right you can have a flock that is low maintenance, low drama. I think it is worth it but it takes faith as the beginning stages take work before you start seeing a return and it's tempting to cut corners or put off doing it right till later. problems are much harder to cure than prevent.
that's my two cents but there are many approaches and opinions, you'll need to measure and balance them all as best you can. most of all, have fun!
