I have small free range turkey flock that I supplement protien with sport mix 26/18 dry dog food they seem to do quite well with it I am not sure why this would be considered a bad practice as my Great Danes seem to do well on it also lol to each his own I guess ,,, I have been hatching for quite a few years and have great hatch rates with my methods and others have good results with theirs what works for me may not work for you or visa versa just saying
