I have learned recently that chickens cannot digest oats or barely because they lack enzymes in their digestive system needed to break them down, it is something to do with beta-glucagon forming gels in the gut that can't be broken down, which means the chickens need to eat more of to have enough energy. I have now adjusted my feed mix to that removing all the oats and barely and replacing them mostly with whole wheat and maize. My chickens do actually look a little bit more active energetic already and my feeders are emptieing more slowly so I am saving on feed (wheat is actually cheaper that barely and oats aswell because it is not fed to many animals and the hens don't need as much to provide them with energy)
Hmm, I wonder if fermenting oats or barley helps create/activate those necessary enzymes so they are present in the feed...the bird consumes the enzymes along with the grains. Anyone know? I am going to look this one up
