My mom has a bunch of chickens (10, actually. I'm also helping her raise 4 ducklings and 3 chicks), though I often take care of them myself(of course, I live here rent-free, so it's justified that I get the work).
Just some advice:
-Put some thin fencing with smaller holes in it (can probably be found as "chicken wire" or "chicken fence") over the top of whatever you've got them in. Chickens can jump hella high, even as little chicks and it would not be a fun day when they discover that escaping is easy. As someone who has chased chickens; avoid having to do it.
-Change the bedding every 2-3 days, even if it doesn't look bad. Chickens scratching the ground turns up the bedding and it can get really nasty-smelling if left unchanged. And I recommend that you use straw instead of other stuff. Straw is cheaper and easier to clean up. Comes in heavy-ass bales, but it's cost-effective and works super well. I put paper or heavy-duty plastic underneath the layer of bedding in the chicks'/ducklings' housing so that it's easy to change out without having to fully clean the housing every single time.
-If you don't have a coop built, try getting that done before they get older. If you already have it done, then I look like an ass, but it's something a lot of people had done and realized that they dun goofed.
-Something I learned quickly for keeping coop feeders and waterers clean: elevate them. Feeders in our coop hang from hooks we bought at Lowes for cheap and old dog leashes that we don't use anymore. It keeps the chickens from spilling anything (including crap) into their food. Requires much less cleaning and food doesn't get needlessly spilled onto the floor. Our water was put on top of an old tire. Keeps them from scratching so much straw into it and they have to face it to use it, so no crap gets into the bowl.
-Don't let anything get broody. We have this one Brahma that got broody once and she didn't lay eggs for a long time. We ended up giving her eggs to hatch (we got 2 Easter-eggers from that) and she started laying again, but we got lucky with that. Normally when one goes broody, it stays that way.
-Roosters aren't bad to have. Just don't keep more than like 1-2. Fertilized eggs don't taste any different than non-fertilized. Just make sure to empty the nest boxes every day or two. Roosters can also peck hens when trying to do their thing, so check on the hens from time to time and make sure none of them are hurt. If they are hurt, separate them - other chickens will make it worse because they're assholes.
Might take some pictures of our stuff. Been keeping chickens for over a year and have helped raise 3 groups of chicks. It's way easier than you'd read about on the internet, TBH. Give them the right food, proper heat, fresh bedding every few days, water, and they mostly take care of themselves. Very much unlike human children. When the chickens mature, it actually gets even easier.
