Welcome to the Dark & Feathered Side :encouragement:
I got my first pullets (no chicks for me!) 10yrs ago & have been through every conceivable Chicken Trauma since, but the eggs make it worth every shed tear & gray hair.
And, surprising to me, there is a whole lot of personality in 5# of feathers!
First off, as @Bluey & @Simkie said: Everything likes chicken, so a varmint-proof coop is essential.
Chicken wire fencing eventually rusts (mine went in year 9) so hardware cloth, while pricier is a better investment.
Fencing needs to go about a foot underground to keep out digging predators & bent outward for that same reason.
I splurged and had electric run to the coop & it has saved me a lot of trouble.
A light to see in pitchblack mornings/evenings, outlet for a heatlamp & heated waterbowl. I use a 1/2 gallon heated dog bowl from TSC, for my now-3 (had 7 at one time) it keeps water liquid even in Polar Vortex temps.
I freeranged my hens - losing 3 in one day to a fox - in daylight - until an across-the-road neighbor complained they were scratching up her mulch.
For that I blame the Oops! Rooster - got 2 chicks from a friend & 1 was a Him. Prior to him, my hens never left my property.
So now they are in Chicken Gitmo < their fenced yard & have enough room to stay happy.
P.S.
I will never knowingly get another rooster. I know some folks have friendly males, a friend had one huge guy with spurs a good 5" who could be picked up & carried like a stuffed toy.
My guy was the other kind - a mean sumbitch once he hit puberty.
My coop is a re-purposed garden shed - former owners kept poultry - so tall enough for me to stand upright inside.
I scoop poop daily using a scoop intended for a litterbox & bed on shavings that I change out completely each Spring, sprinkling Sevin dust on the new bedding.
Chicken Wisdom states hens prefer roosting on something wide enough to get their toes wrapped around, so I provided some tree branches stripped of bark - rustic & decorative besides being the supposed preferred diameter.
But all my hens (3 different sets now) seem to prefer the lath-width - so less than 1/2" - top edge of a partition at the front of their coop. Go Figure.
Breeds can vary in personality. I had standoffish Black Stars, SoSo Delawares, a Wyandotte mutt who did not live long enough to know & a Houdan who went against standard by being my friendliest hen.
Current group is a crossbreed - Barred Rock/Leghorn? - freebies from an Amish guy downsizing. They are good layers of Xlarge brown eggs & once they got familiar with me, pretty friendly.
Mortality is something you have to get used to.
Some live long, others keel over for no apparent reason & some get diseases that are hard to treat with not great outcomes. One with sour crop taught me how to make a chicken barf :rolleyes: & I still lost her.
As Prey, chickens do not act sick until they are nearly goners.
All of that considered. I will have hens as long as I am able.
They are low maintenance & amusing pets & as the saying goes: They make me breakfast :winkgrin:
