Options for feeding mixed flock

[Oldhenhens]

I have 35 chickens in the coop. First group (one rooster and 10 hens) has been laying for almost a year but going through their molt right now. Then I have my 24 “teenagers” (5 cockerels and the rest pullets) who are 16 weeks old. Plus I have my 34 “chicklets” as I call them in an intermediate coop. They are all 4 weeks old and a mixed flock of 31 chicks and 3 keets. They are on medicated chick started but I was told to give higher protein turkey starter due to the keets. Can I do a mix with both chick starter/grower and turkey starter or just turkey starter?
Also, I was told I can also mix the higher protein turkey starter in the layer feed to give the molting hens some added protein.
What do you suggest? Sorry my question is so long. Thank you for your thoughts and advice.

Give everyone non medicated chick feed (20%) protein, you could even give everyone the gamebird feed with no side effects, (my chicken go nuts over it) oyster shell on the side

I give my mixed flock an all flock feed and supplement oyster shells & eggshells on the side for the layers. Most flock feeds are at 18%-20% protein.
You don't need medicated feed though - it's generally a preference and cocci are local to your environment so even some of the chicks that start on medicated feed end up with coccidiosis.
