Pellets are a better regular, daily diet than seed-mix because they contain less fat, but they have to be introduced to them early in the weaning process, however I would definitely at least buy a bag of them and mix them in with their bowl of seed mix to allow them to start picking at them, and eventually they can make the transition over to only pellets, or what might actually be better for you is feeding them a mix of both...
What seed-mix are you feeding them? Is it a commercially-sold seed-mix, or are you just making your own seed-mix out of loose seeds? I don't know what you have access to buying as far as seed-mixes, pellets, etc., I know it's most-likely different than what is available in the US, but I could be wrong...If you want to start to introduce a pellet to them with their seed-mix it's a good idea, certainly can't hurt and the sooner the better...As far as exactly which pellet to give them, it all depends on what you have available to you...The "fruit-flavored" pellets, meaning the multi-colored pellets that are usually red, green orange, yellow, purple, etc., are actually very, very high in sugar content, which gets turned into fat and stored in their Livers just like the fat from the seed-mix does, and the same goes for any pellets that are "Nut-flavored", but they are much less common than the fruit pellets...So it's better to give them a "Natural" flavored pellet, as they have no added sugar...It's just going to depend on what you are able to buy on a regular basis, the same goes for the seed-mix you feed them...Can you give me an idea of what brands/types of pellets and seed-mixes you have available to you and that you can buy on a regular basis easily? Then I can give you my best choice for both a pellet and a seed-mix...What seed-mix are you currently weaning them onto? I remember you mentioned something about an "ND" seed-mix, but I wasn't sure what you meant by that...I'll be honest, I have no idea where in India you live or what types of parrot foods are sold there regularly...I'm assuming that if you live in a city in India then it's not going to be too different than what is sold here in the US, but I'll be the first to admit that I know very little about India...I was in Delhi once years ago on a graduate-school trip for 2 weeks, and it was absolutely gorgeous, just breathtakingly stunning, and I absolutely LOVE authentic India cooking, which is extremely difficult to get in the US unless you live in a very large city like New York or Los Angeles...So I loved the trip, I gained 15 pounds in the 2 weeks I was there eating nothing but different Kormas and other Curries, lol...But I saw no parrots at all...And it was HOT!!! SO HOT!!!
As far as their weights go, they both look healthy, and the difference between them isn't really too noticeable, so I'm not really concerned about that too much as long as you keep weighing them every morning and making sure that neither of them start losing weight every day. I'm very happy that they both have already Fledged, so that means that they both should not lose a bunch of weight suddenly, if anything they should have both gained a little bit of weight after they first Fledged, and from that point forward they should both have their weights stay pretty constant. Parrots are just like people in that some are larger than others in height, weight, etc. So it's quite possible that two parrots of the same species and even from the same clutch (siblings) are very different in weight, height, length of their legs, their wing-spans, etc. All that matters is that each individual bird is at a healthy weight and is eating a proper amount of their "staple diet" each day, meaning their main food source, which is either a seed-mix or an avian pellet, and then also eating a portion of fresh Veggies and Greens each day...
Living in India you have access to a really large variety of dark, leafy Greens that we can't buy over here in the US unless we're lucky enough to have a real Indian, Thai, etc. market, which again only exist in large cities...We're lucky to be able to buy Bok Choy in our regular grocery stores! And the same goes for the fresh Vegetables that you have access to...Parrots can eat ANY fresh Vegetables and Greens except for any in the Onion family or related to the Onion family, for example no Onions of ANY KIND, NOT EVER, and the same goes for any types of Leeks, Chives, etc. Any and all Onions and their relatives are toxic/poisonous to birds, so they can't ever have them...However, other than the Onions, they can eat pretty much ANY fresh Veggies and Greens, and that includes ALL of the wonderful Peppers that you have access to!!!
I meant to talk to you about this before, but birds LOVE all types of Peppers because they don't have the receptors on their tongues for capsaicin, so they sense any of the heat from any Pepper, even from the really hot ones like the Ghost Peppers, they only taste the actual taste of the Peppers. My guys LOVE all of the regular Bell Peppers we have here, like the Green, Red, Yellow, and Orange Bell-Peppers, and they also love Chili Peppers and their seeds! So since you have access to tons of different Peppers as well, your birds will absolutely LOVE not only the fresh Peppers chopped-up, but also the seeds from any of the Peppers, either the seeds fresh or the seeds out of dried-Peppers. They are not only healthy for them, but Pepper-seeds are like a treat to birds, that's how they think of them, but they are extremely healthy for them, so they really aren't treat at all...
Have you ever made any type of "Chop" recipes for your birds yet? "Chops" are just different recipes for mixes of fresh Vegetables, Greens, Fruit, and sometimes grains, legumes, seeds, nuts, etc. also mixed in...There are literally thousands of recipes for different "Chops" in the Food and Diet section of the forum, and you can really experiment with any and all Veggies, Greens, Fruit, etc. that you have access to...It's all about trying different recipes and finding out what Veggies, Greens, Fruit, etc. that your individual birds like...When you make a "Chop" or you give your birds fresh Veggies, Greens, and Fruit, make sure you're chopping them all up into small enough pieces for them to easily chew and eat. The possibilities are endless for the Veggies, Greens, and Fruit that you can feed them, and if they are eating their fresh Veggies, Greens, and Fruit more easily than the seed-mix, then something I suggest trying is making up batches of "Chop" with lots of different fresh Veggies, Greens, and Fruit, but ALWAYS mixing in a good amount of their seed-mix (and pellets if you start feeding them) into the "Chop", and by default they are going to eat a good portion of the seeds and pellets while eating the rest of the "Chop"...
******Just make sure that you TOTALLY AVOID the following Vegetables, Greens, and Fruit, as they are either Toxic/Poisonous to your birds, or they contain way too much Vitamin C for them:
-All Onions of any kind
-Leeks
-Chives
-Avocado
****All Citrus Fruit should be either totally avoided, or at the most only given once a week in a very, very small amount. The reason that you can't feed your birds much Citrus Fruit is because it is all very high in Vitamin C content...When you eat Vitamin C and it is absorbed by the body, it immediately enhances the amount of Iron the body absorbs from the food that is eaten...And birds not only don't need much Iron in their bodies at all, not even close to the amount of Iron that people or other animals like dogs and cats need, but birds actually become extremely sick if their bodies absorb very much Iron at all. They can quickly develop a disease called "Iron Storage Syndrome", which is fatal if not reversed by an Avian Vet. Once Iron starts being absorbed by a bird's body, it is stored over time, and if they eat Iron-rich foods or Vitamin C-rich foods on a regular basis, the amount of Iron in their bodies builds-up to the point where it basically starts to poison them. So while it's perfectly fine to feed your bird a small piece of Orange, Grapefruit, Lemon, Lime, etc. once or twice a week, they can't have it every day, and they cannot have large portions...THIS ALSO INCLUDES ALL TOMATOES!!! TOMATOES ARE A FRUIT, AND THEY ARE VERY HIGH IN VITAMIN C CONTENT!!!
