Most of my flock is currently in their yearly molt and eggs are a distant memory. I'm looking for suggestions on what to serve my flock during this time to help build the best feathers possible. From my reading I see that feathers are mostly Keratin and I would think I should increase items high in this item during molt time. What would you suggest as top items? I've seen pumpkin, yogurt, whole grains, peanut butter, corn, animal proteins, and sulfurous items. Does anyone have a preference on theses items? Currently I serve my flock primarily Purina flock raiser (oyster shell available) but add in some Purina Game Fish chow once a day for a treat for the additional protein boost.
