Sorry that you took my post tone way wrong; you focused way too much on the one thing I said in the first paragraph and ignored the 2nd based on how you interpreted the message.
I wasn't telling you to stop making suggestions; I was suggesting that you be less focused on it it and understand that there are limitations and we sometimes have to live within them, because you seemed legitimately upset about the issue. You use the term "aggravating" in your OP even. My point was to advise you to stop trying so hard to pound a square peg into a round hole and just use the round peg for now...while holding out hope that they will make the hole square down the road.
As I said....I actually like your idea. I too would be happy if they implemented it. But I'm not going to be aggravated or annoyed over it in the short term because, as with any game, I took the time to learn to play successfully within the constraints presented me.
Suggestions are good, keep giving them....but don't have expectations that they "need" or "must" be implemented. The game is already solid, and fun; you're just hurting yourself if you focus too much on the limitations where they exist instead of the good stuff where that exists.
So what if for every feeder we could select the refill frequency. The default could remain for the keepers to fill as they see fit, but players could also set for keepers to automatically fill every 3, 6 months, etc. I would like to see this trigger the keeper AI to prepare food before ever entering the habitat, which should also greatly increase their efficiency (rather than walking in, looking around, walking to the keeper hut, and then walking all the way back).
I really like this idea. Since the first day I started playing, when I tried to add a second keeper gate to a large habitat, being able to maintain and keep my animals fed and the habitat clean when there are a lot of animals in an enclosure has been something I've wanted more control over. It's not like the current keeper AI does a good job of food control anyway, as a lot of the time a ton of it still goes to waste and spoils.
I see nothing wrong with a re-write of the AI to do things as you suggest, and more player control over the mechanics of it in this kind of game is always a good thing.
It doesn't solve the issue of habitat cleanliness though. And for me, that's a way bigger issue than feeding. I have never had animals starve, even with 30 or more in a single habitat. What I have had is frequent cleanliness warnings and disease outbreaks.
@Ashen Shugar touches on this above with the 20+ peafowl example. I've never been able to keep a peafowl habitat clean once it breaks around the ~20 to 25 animal mark. Have had the same issue with Reindeer in the arctic pack with just the 10 reindeer in the first career scenario, once they had babies.
Honestly though, cleaning has an even easier fix than feeding. Let us set the frequency of keeper visits for cleaning and for feeding separately and allow the frequency to be higher than 1/month....problem solved.
I think I even cracked how to get more than one keeper into a habitat cleaning at the same time yesterday with those reindeer, as I saw it happening more than once....didn't help, it still got dirty and I got diseases before keepers were cleaning it, simply because the duration of 1/month was too long regardless of how many keepers go to clean once that threshold was hit.
