EXACTLY! We do NOT feed them their natural diet, especially when you feed pellets which are not only processed but have lab-made vitamins! (I've eaten Harrison's pellets -they are VERY bland and dry although they do have a mild grainy flavor to them -not disgusting at all but nothing anybody would choose to eat unless they are into eating cardboard -LOL).
As to why to screw around with anything that is not natural? Because we screw around so very badly when we make them pets! Life in captivity is HIGHLY unnatural so it falls to us to provide substitutes for wild behaviors. Foraging with their flock is not only part of their natural behaviors, it's one of the most important ones. There are now studies that tell us that when a flock is eating, the ones in the periphery keep an eye out for all the birds that eat in 'the middle' and while they just lower their heads and eat, the 'watch' just pecks here and there, lifting their heads constantly to look around for predators. Eating with the flock makes them feel secure which translates into no stress and a bird that eats on its lonesome is not going to eat as well as one that eats within the security of the flock. Not my opinion but a fact. Now, the birds in my birdroom don't need as many substitutes as Zoey because they all live together and have come to accept each other as part of a weird but workable flock but Zoey has nobody but me so the onus is on me to make up for the lack of flock. This means spending hours and hours with her, taking her with me when I clean around the house, take a shower, etc. And part of this routine is the quiet shoulder time she spends when I sit at the computer. During this time, I drink my tea and it would be quite confusing and upsetting to her if I did not share (flock mates share - always!). She doesn't drink from my cup (she has her own, a pink demi-tasse from an old espresso set), she doesn't drink anything that would be bad for her and those couple of small sips (she doesn't really drink more than that) make her feel that she belongs, secure and loved so, as far as I can see, it's all pros and no cons.
As to links for the herbs, there are millions, just google linden, chamomile and star anise (I don't use the tea bags but the herbs themselves and I get them at Mountain Rose). I also use cedron (a South American type of lemon verbena), boldo (same name in English and a good liver tonic), carqueja (don't know the name in English but it's also great for the liver), marcela (again, don't know the name in English but it's great for digestion) and hierba de pollo (same thing, no idea of the English name but very good for digestion). Back home, a very mild tea made out of linden, chamomile, hierba de pollo and star anise is given to infants instead of plain water and my children grew up on it. (I get the South American herbs from back home but some are available online).
