One reason I ask, is that Tobie having made it through a very heavy molt seems to be craving protein. He loves eggs, fish and most any meat. Tonight he ignored his fruits and veggies and kept looking at my plate and stretching his neck toward my plate. I cut a peice of rib eye and he held it in his foot and devoured it - a pretty big chunk. If feathers are made of protein it seems that during a molt a bird might need more protein. Another thing I've thought about is their beaks are shaped like a hawk, buzzard or other birds of prey and not like a nuthatch, chickadee, cardinal or other seed eater. My pellets though have oats, wheat, corn and vitamins and minerals. Odd, don't you think.
