x2I don't think that the 'seeds and grains' type of diets work out as well as crumbles or pelleted feeds. The birds will pick out the tastiest stuff and leave the rest, and the vitamin/ mineral mix sifts to the bottom and isn't eaten well enough. Getting back to a good all-flock feed with separate oyster shell is best, IMO. I don't feed the lower protein 16% stuff either.
See if things get better over time, at least a few weeks.
