I do not recommend feeding medicated starter to poults. I am not aware of any proper high protein (28% to 30% protein) available other than a medicated starter that Purina sells specifically for a disease that quail can get.
Normal medicated starter feeds contain amprolium meant specifically to combat coccidiosis. Amprolium is a thiamine blocker which is one of the vitamins that poults need for proper development. If coccidiosis is not a problem, one should not feed this type of medicated starter.
You did not mention what your bedding is. Poults should not be on wood chips until they are at least 2 weeks old. They can eat the wood chips, become blocked up and die because they cannot digest them without appropriate sized grit in their system.
Many people use a brooder that is far too small for poults. The brooder should be big enough to have a warm zone and a cool zone.
I use a 4'x4' brooder with a temperature controlled GQF brooder heater. It is set to control the temperature at bedding level at 90°F for the first week. The waterer and feeder are set in the cool area. The waterer is filled and allowed to warm in the brooder before any poults are added.
I use sand for bedding because I live on a sand dune and the sand is free. Poults have different instincts than chicks. It is instinctive for them to peck at things on the ground. I sprinkle the high protein (30%) starter feed on the sand. The poults usually start eating within minutes of being placed in the brooder. It may take them several days to start eating from the feeder. Until I see them eating from the feeder, I continue to sprinkle feed on the sand.
If I lose one poult out of 100, it is because the poult had something wrong with it and would have been culled anyway.
