I would say that as long as she's eating and pooping normally, then it's probably fine that they don't want to be with each other. There are times when Dakota and Flopsy don't like to lay by each other to snuggle. I think our buns are a bit like us and just need time apart sometimes.
You may want to wait on the oats until she's had several consecutive days or even a week or two, of eating good and no health issues. If you want to give treats it would be a lot better to start giving her leafy greens. I would start gradually, one at a time, just to make sure that she's ok with them. If it ends up being the pellets that were the cause of her problems, it would be because pellets have grain and sugar in them, so giving her oats might just start causing problems again. So give veggies for treats instead, and just give it some time before you try anything like oats, and even then I wouldn't give more than a pinch of them, but be aware that if her problems were GI issues, and if she is susceptible to them, then giving extra grains, sugars, starches, and carbs, could just start this all over again, it could even be worse next time. If after a while you do try introducing oats or maybe a piece of carrot, I would start with very small portions(like 3 pieces of oats or a very tiny piece of carrot) and keep an extra close eye on any changes in her poop, because that will be your first sign something is wrong, even before she starts showing any signs of feeling sick. I would think Zeus was better, and all I tried to do was gradually change his food to a new one, and he would get sick again.
Kiwi's diet sounds good, unless she keeps having tummy upset, then you may need to decrease the pellets more. But as long as she seems to be feeling ok and her poops look normal with none of those really small ones, then I think you can stick with what you are doing. And you could start adding the green leafy veggies in. With Papaya, unless you think he needs that amount of pellets, he could probably be ok with more. My Pip is only 2 1/2 lbs. and she only gets a 1/4 cup. So if he weighs more than that, and since he wasn't having stomach problems, you could probably give him 1/3 to a half cup a day, depending on his weight. And he can be getting veggies too. If you want to do treats with him and he hasn't had any problems, then it might be ok, just don't let Kiwi see
Those hay cubes should be just fine as long as it's just hay in there and nothing else added.
Lol, I can totally see your horses doing that. I found that no matter how hard I tried, Deniro would find ways to get into trouble. When he was down at my brothers' property, there was a bin of grain in the tack shed, and the shed was in the horse pen. Well apparently it was too irresistable, so Deniro ripped the lock off, broke in the tack shed, ate all the grain, and chewed up the saddles. Naughty, naughty horse. He was in big trouble after that
