I'm sorry you are feeling overwhelmed. Chickens can be incredibly easy IF you have the right setup. If you don't, they can be quite overwhelming, and can be unhappy themselves as well as making you unhappy. There are some chicken basics that keep being repeated over and over on newbie threads by the experienced users, but I don't know if they exist anywhere as a bullet point list to point you to... Here are some examples:
- Space. Extremely important. Both your coop and your covered run are way too small for the number of chickens you have. Small space + too many chickens = too much poop and smell. You need at least 4 square feet per bird of coop space, and 10 square feet per bird of run space.
- Free ranging. I don't know if you intend to let them loose all over your property, or if that's a product of them crying and not wanting to stay confined to their covered run, but keeping them loose like that means there will be poop everywhere. You can't walk around your yard or go down your steps without stepping in poop. I don't know how big your whole property is, but what's in the pictures looks very small. Chickens need space to roam, but you need space as well. Sharing the same space will inevitably result in conflict, even if just the frustration of poop everywhere. On a larger property, there's more space for the chickens to spread out on, and the poop is more spread out as well, but free ranging in a small city yard is not a good idea as it will concentrate the poop in a smaller space. Free ranging is also dangerous because of predators, so expect more losses if you don't keep them in a predator-proof run.
- Bedding. That grass is nice but it won't last long. Your chicks are still young, but as they grow, they'll get more and more destructive. They love to eat and scratch through grass. You'll end up with bare patches that will get muddy when it rains. Grass is also really hard to clean from poop. You can't rake it, can't bury the poop in bedding, the poop doesn't compost easily. Washing poop away isn't a good idea. Wet poop smells. The way to control smell with chickens is to keep everything as dry as possible, not wet. And you need some sort of bedding for the run, not just grass. Wood chips work amazingly well and are popular with a lot of folks. That, and other organic material (organic in the sense of "plant material" as opposed to sand or rock, not "organic" as the fancy buzzword of the hippie food industry). Dry fall leaves, mowed grass clippings, yard waste. Mix it all up. When combined with the poop and moisture from weather, it composts in place and doesn't smell. That's what I have in my run. I don't clean my run, and it doesn't smell. The chickens mix it around and it composts. I have a thick layer of pine shavings inside the coop, and it doesn't smell either, but I have a large, roomy, airy coop with lots of ventilation. Small, cramped coops are hard to ventilate well, coop concentrations are higher (unless you clean every day) and they tend to smell.
What I would recommend is building a proper coop and run that can hold the number of chickens you have, following the above recommendation for square footage. If that would mean making it bigger than what you'd want to sacrifice from your yard, then scale down the number of chickens, but don't compromise on their space. Remember, space too small = too much poop concentration = smell. So figure out how big of a structure you are able/willing to have in your yard, and how many chickens can fit in it. Then build a properly sized coop and run for them, give them adequate bedding, points of interest in the run (things to climb on, hide behind, dust bath to roll around in, etc.) and keep them inside the run so your whole property isn't pooped on, and you'll find that chicken keeping is a whole lot easier. Good luck!
