I have used hand-made monkey biscuit based formula for day one quaker babies. I raised them from day one on Kaytee for many years then out of curiosity switched to a hand-made version since so many old time breeders had such better weight gains using their own concoction. It made a huge difference in growth rates and hydration of day one chicks. I was able to much more quickly get the babies up to thick formula, fast weight gains and good skin color on the hand-made stuff. However, I also had problems with them potentially gaining too much weight toward the later stages. Personally, I like to do a modified formula for early day ones but stick with plain Kaytee for babies after about 5-7 days.
Even at that rate, I discovered that an easier way to keep chicks hydrated and yet able to consume thicker formula from day one is just to add about 10-20% gerber baby rice formula for the first few critical days. It gets more nutrition into them but holds the water in with the formula so there isn't so much separation and the babies grow like parent feds or close to it. However, because that rice formula is made for human infants, I strongly advise against using it beyond those first few days when hydration is so critical. I would be quickly phasing it out by day 5. When I used to do quakers, I'd start them on 20% rice formula and 80% kaytee for day 0-3 fed as thick as I could but not get crop slow down, then 10% rice formula until day 5. By day 5 if not before they were taking kaytee plain just a smidgen thinner than full thickness. Regardless, after much experimentation and with the species I've bred(quakers, parrotlets, amazons, cockatiels) I'd be sticking with regular nothing added Kaytee after the first week unless you are specifically having hydration problems or instructed by a vet. Its just so much easier, and it just plain works better. My hyacinth was raised using an old time hand-feeding formula by her breeders. They tend to get higher weight gains which is good for a high fat quick metabolism macaw. However, their feather coloring isn't as vibrant as babies fed manufactured formula and for the huge majority of species that don't need gobs of extra fat that might lead to obesity, stress fractures on still growing bones and liver problems, I'd just stick with Kaytee.
