I got chickens initially because I couldn't walk from my back door to my workshop during the summer without having to pick ticks off of my legs. Eggs were an afterthought.
We keep barred rocks, trying to keep the flock at around a dozen. They're good layers, hearty in our weather conditions, and excellent foragers. Place called the 'Cackle Hatchery' is just a few miles away, we generally buy chicks there and raise them ourselves.
They absolutely worked for the ticks. I seldom find any around the house. My Great Pyrenees brings ticks in from all over the area... he will regularly lay in the sun while half a dozen hens pick him clean. He really seems to enjoy their attention. Of course, the Pyr is here mainly to protect the chickens... we're way out in the woods, lots of coyotes, possum, raccoon, fox, bobcat. Rambo does a good job of keeping them safe. About the only losses we get are from birds. Red tailed hawks and barn owls. We count on loosing 1 or 2 pullets to bird strike after we put the new chicks out each summer.
My initial coop was a 'chicken tractor' type, where it doesn't have a bottom, and you're supposed to move it around as the waste builds up. Didn't work for me, I ended up raising that chicken tractor up onto a solid wood 'box' that I built for it from a couple of 2 x 12's and a sheet of plywood, and using a fairly deep bed of pine shavings as an absorbent in the bottom of the coop. It's located under a metal roof off of the south side of my workshop, right next to my dog kennel. Works great. Doesn't stink. We have to clean out the laying boxes and add shaved pine every month, but we only have to really clean the coop once a year. Pull the top off and shovel out the old pine and waste. It'd probably make good fertilizer, but I just dump it in the woods.
Mouse control becomes a problem... spilled chicken feed will bring them out in mass.
Amazon sells 'roller traps' that work pretty well. No danger to the birds.
BackyardChickens.com, mentioned above is a good resource. We use the 'deep litter method' that they document with excellent results.
