Pros & cons of high protein feed for chicks

[Cyprus]

Ok, so are people actually reading the (old) NRC guidelines and choosing which feeds have the nutrients their birds need, are they crossing their fingers, or is there a source somewhere that says whether all of these various types of feeds, marketed for different species and.purposes, are appropriate for X species at Y life stage?

I can look and see if I find anything.

Cyprus, I agree about the lower protein layer diets. 16 is just not enough. I am going to look in to the PGB 30% and might want to try that. Thanks for the detailed info about how your flock does on the higher protein.
