Excess protein damages kidneys--period.@ChickenCanoe
I have seven 25 week old laying pullets and eight 5-6 week old chicks. While they have been integrated I still have the in-coop brooder in place and keep separate feed and water for their exclusive use. They also have access to the pullet feeders and water both in the coop and in the run below; I see them feeding from those locations and also from a dispenser that holds crushed oyster shell in the coop proper.
I wanted non medicated feeds and buy from reputable local feed suppliers, in both cases the feed is manufactured on-site. The only grower feed I could find is designed for ducks an has a 22% protein content, otherwise has "appropriate" balance of other ingredients; I will have to check for the specific of amino acids per your comments. I was hoping to use only the 22% feed for both groups at least through the winter. I do not give them many treats (certainly less than 10%) and those are limited to vegetable scraps and scrambled eggs.
Thanks
