each is organic. I go between a Blue Seal brand and one from another local feed store. I haven't noticed any major changes in feathers or eggs--but I started after feathers had been eaten, so they look scruffy, anyway. The eater is my white leghorn--she always has done. Maybe the feather piking won't stop until she's gone to heaven.
have noticed my leghorns are bad about feather picking when locked up but when they are out free ranging they don't do it even when they come in to roost at night
