Maybe share some ideas on how you'd wanna see it improved instead of just whining yourself. And please, spare the complaining on its looks because if that's the only issue you have then there is no issue. That always the problem, people dribble complaints but almost never offer anything constructive.
I've commented on it before... yes, it looks bad and they should have made it look more appropriate. Practically no one if placed in the situation that this game puts you in would make a chicken coop like that. That alone is enough to say it's a dumb choice. But if you like how it looks, that's fine.
There is also the minigame... chickens are already rather uncommon to find (and now that zombies will actively attack and kill them, they'll likely be even harder to find). In order to not have to spend forever walking around doing a minigame, you need to find them close to your base, which may not be possible. Or you have to cheat and drop a chicken coop when you find one and put it in there to stop the minigame from happening and then carry them back as inventory afterwards (assuming that actually works since I have no interest in attempting to cheat that way). So you need to find them close if you don't want to walk forever in a minigame where you can't use any vehicle. Since the chances of finding one close are a bit low, you're almost forced to spend a point in the perk to track animals... a perk that I never use and don't want to waste any points in. It might only be one point, but it's a point I don't need or want to spend there. There are plenty of other places to spend points in the early game that are far more useful. Then there is the minigame stress events and I think Kyoji explains the problems with those pretty well.
And then you have the lack of value from it. Relatively low percentage of players (my guess, but I think it's accurate) continue to use eggs after the early game (the first week or less) as they get better food choices. That means getting eggs isn't needed for most players. Feathers are also something that most players aren't going to really need. If you're not using them for arrows, there's little need to keep getting them. And since you can collect your arrows/bolts if you don't lose them, there's normally not much need to make a ton of them unless you don't want to collect them or you use them for horde night and can't collect them before they despawn. The chicken coops don't provide regular meat, which means it doesn't help you with any food recipes other than the new ones. So for it to be useful after the first week, you need to either be someone who always cooks food with eggs (and you'd still have to go get regular meat since the chicken coop doesn't provide that or only make pies/cakes) or you need to be someone who uses a ton of feathers or you need to want to cook the new food items. Otherwise, it's pretty pointless after the first week. If they dropped the "domesticated chicken" output and put regular meat, that would at least make it useful for meat and all your recipe choices that use meat. But even then, meat is hardly difficult to get even if you don't try (I always have tons of meat sitting there and I don't normally go out hunting unless it's end game and I just want to complete the challenges).
Instead, we have a chicken coop that doesn't provide regular meat even though killing a chicken provides regular meat. We have recipes that can't be made with the meat you get from killing a wild chicken even though it's a recipe requiring chicken meat. We have a new kind of meat that is specifically chicken while all other animals provide generic meat. Want bacon and eggs? No need to find a boar... just kill a deer and you can have bacon. Although that's kind of dumb, it's just a way to have all meat be a single item that is used in all recipes. But now we have a special chicken meat that isn't even meat but a living "domesticated chicken" that we're going to cook into chicken recipes while leaving all other meat, including wild chicken meat, as a generic meat that can be used for everything except the new recipes. We have a minigame with stress reactions that are poorly thought out. We have no way to transport a chicken we catch and are stuck walking long distances or else cheating it (assuming that works). We have output from the chicken coop that, for most players, isn't needed after the very early game and just requires you to spend constant resources to feed them to get something you aren't going to need. We have a chicken coop with the red light from the heater that shines through solid blocks if you place it near your base. And we have a chicken coop that looks like this is a Disney game that doesn't fit the with all the other workstations. At this point, why not include a plastic kids play table for the workbench and combiner as well? Or a kids play kitchen for something to hold the campfire? We can use an Easy Bake Oven for cooking. And, no... I don't think that should be done any more than I think the chicken coop should be a playhouse.
And I have a feeling the majority of people who have been asking to raise chickens (have a chicken coop) in the game are going to be very disappointed. For people who want to raise chickens in the game, they would want to SEE the chickens. They would want to have them walking around. There's no value to someone who wants to raise them to just have a decoration that supposedly holds chickens that doesn't show the chickens or allow any interaction with the chickens. So even most of those who wanted this over the years probably aren't going to like the implementation either.
But as I have said before, regardless how bad this was implemented and designed (yes, it's my opinion and you can have your own), it is something that I never have to use in the game since it's pretty useless anyhow, so I don't really care if it's there. That doesn't change that I think it's badly designed, looks horrible and out of place, and is pretty pointless as anything other than a decoration for those who want chickens. It can be there. It can be left looking dumb (maybe someone will be kind enough to make a mod to change the model). It can be left with a poorly designed and thought out minigame. It can be left with no visible chickens or interactions with the chickens. It can be left with not providing real meat that can be used for normal cooking recipes. In the end, it doesn't really matter since I don't need it and won't ever have to put it in my game. Maybe they'll choose to fix it. Maybe not.
-- but you are still wrong to claim that the chicken coop is the only added content we get, since they add content quite regularly. And that was what I commented on.
