OK; then I would follow your instincts as expressed in post 4
Use as many bowls placed apart as necessary for all birds to eat at once. Do not leave food laying around - everyone should have had their fill after about 20 minutes. If they are not confined and can forage, let them for the rest of the day, and then offer your feed again before they go to roost. Ensure there is plenty of fresh clean water at all times. Good luck.
rather than the fixed items and quantities in post 1. Birds have evolved to select a balanced diet as best they can from what the seasons provide. Supply a variety of fresh local produce - grains and seeds that grow where you live, supplemented with some meat, fish, insect, dairy (animal protein in whatever form you can get it and is legal where you are), and observe. Trust your birds to select what they need in the amounts they need, and adjust your quantities through the year accordingly. You will get a good idea of what's needed within a week or two. Expect it to change. One size does not fit all the birds in your flock from day to day, never mind every day. To begin with they will be desperate to source the nutrients that have been lacking from their current diet; it will settle down soon.With the pallets being too high in protein and not providing the birds with the other things they require, and the seed mixes being the opposite with not enough protein.
Over the years I have observed that the seeds mixes at least the cheaper ones have started to lack a verity of different seeds with it now mainly being rice and corn, causing the mixes to not provide a balanced diet and lack in protein
