My hens look like a real mess--feathers all over the pen, and they are scraggly as I don't know what. Seems like I saw somewhere here that extra protein helps them grow their new feathers. I got a sack of game chick feed, which is way high in protein, and have 2 feeders in the henhouse--one of the game bird feed and one of their normal egg pellets. They seem to be eating only the game bird feed. Is this because they sense they need the protein, or is it maybe just tastier, and if this is the case, will all this additional protein hurt them??
