I was wondering what would be the best thing to feed a chicken to help it gain some weight? My Buff Orpington is really healthy, but I'd like for her to gain some more fat/meat around her breast area. She's pretty heavy, but I think she's a little too boney in that area. She's about a year old, if that matters. Any suggestions? Also, is it alright for chickens to eat sweet feed along with regular chicken feed? The kind for horses, not cattle.
