Remember, now that Phoenix is on 1:3, for the next 72 hours, their ratio will be slowly changing to 1:2. So each day will be slightly different.
Eventually the youngest will also end up on the 1:3 ratio, but by then Phoenix should be on 1:2.
It will only be when the youngest chick is a week old that they will be able to share the same formula.
This is why I recommend writing all this down. If any more chicks hatch, this is gonna get so confusing, very quickly. You need to be able to know exactly what you are feeding everyone.
