I'm feeding Brown's this year as it's currently the easiest for me to get. Using the developer right now during breeding and pleased with it to this point. What kind of pigeons are you getting, and what are your plans for them? Protein requirements are going to vary depending on the season (breeding, racing, molting, rest etc.). 16% is more of a conditioning mix, and also often used for breeding, but even 14% and 15% proteins mixes are fine for breeding (I'm currently using a 14% mix). A lot of people feed a high protein percentage year round and in my opinion its not good. It's not needed and it's also taxing on the kidneys... the birds will have looser and smellier droppings on top of it. Also if it's during racing you really wouldn't want to use a 16% either... during racing you want to use a lower protein percentage and higher carbohydrate feed. Not sure what your plans are, but Brown's feed is fine as long as you are aware that feed requirements change depending on the season (this goes for any brand).
