A list of Rancher ideas

[Kotlol]

Honestly, a couple of your points are pretty valid, but the rest are kinda ehhh. Chicken RNG is limited to hatching, and even that has a pity system, so your point about a better guide for RNG is literally just adding the "You need a rooster to hatch an egg that ate the feed and it's only a 50% chance" to the Wiki (Or to the book in game, which I feel like you, and only you uses), which you could very well do yourself. The first is covered by Ageinium, PLUS, you seem to not be aware that Ranchers CAN control the chickens lifespan with Ixworth chickens. The Gene Incubator is a so so idea, it could be interesting, but on its own it would require a rework which is more effort than most Devs want to put in for changing chickens a bit. Injecting feed feels like it'd make getting OP chickens pretty trivial to get, the miniscule amount of RNG in Rancher exists for a reason. Also, for that last point, I can't think of a single in-universe way to check the RNG of chickens, so I dunno about that. Sorry if I came off snippy in my reply, but I feel like the majority of these ideas aren't the best in terms of making Rancher more enjoyable (At least to me)  

Showing chances on the wiki would be nice too, but from a newbie perspective, you will use the guide and get frustrated. I don't like "USE THE WIKI" as a defense... if some basic knowledge about: "You may need a rooster to hatch an egg" or such... to inspire experimentation would help alot more then just "FEED X " or "GET A" 
I'm 100% fine with experimentation... but there is no hint to use Roosters for this, that alone in the book would fix newbie frustrations without saying: "USE THE WIKI"
Even the cook book, surgery book and such tell you what to do and so does the botany guide, but the field guide is practically leaving out important information.

That said.. Ageinium is a secret chem, not everyone knows it or uses it. So "using this" as a defense is like saying to an antagonist: "An egg that makes you shrink covers that" ...Especailly on RP where "Secret stuff" shouldn't be common knowledge on the station by someone as random as a Rancher. But that's just me. I still think having growth horomones will be a fun new mechanic ontop of the Agenium that doesn't involve chemistry. Growth hormones can have bad effects after all, thus causing the Rancher to decide to use it or not, wich in term makes Ageinium a safer option.

Also you need to breed ONE TYPE OF CHICKEN, to control ALL TYPES OF CHICKENS. That's not a good defense. it means to be an effective rancher you need to keep making the same type of chickens 1st, before starting on your special chicken project to make it smoother, if this was a long term game sure, but this is a "period game" where you start from scratch every time. If there is a way to speed it up... sure...

As for injecting, yea this is probaly a weaker point of mine. It's more or less based on how there has to be a trade off to control RNG. Like with botany can manipulate seeds but it could cause damage to it or even break the seed. I was thinking of that kinda thing, but maybe injecting feed is "too easy" so maybe another methode that's more risky? Like "mutated" food but it could kill your chicken? Just thinking.

RNG check in universe I already gave a suggestion. Something simple as flavor text when examining them will help alot. For Henks example.. "Rooster, it seems to have a red beak" Showing that it's ready to hatch for Henks.
Then we have from white to brown: "Chicken, Seems to have some brown feathers" Showing it's ready to lay brown eggs, and such. Something as small as that will make it much more easier to see. Heck for raptors I can see. "Does it have a tooth in it's beak?"
Again not perfect.

But atleast you added some good commentary to make me re-think the ideas. And yes.. the egg gene manipulator is defintally the "impossible" idea of the book and I only suggested it to see how it's recieved, I can't code for shit but I even know that THIS IDEA IS PAINFULL FOR THE DEVS! But we all agree rancher needs some side tasks like fishing and Dolly to be more usefull/consitent
