My feed store had 300 pounds of Canadian brown whole flax seeds. Someone ordered them and never picked them up so the owner gave me 100 pounds for $24, a price well below her cost. I've got 6 white breasted turkeys living with my 4 hens and they all eat layer feed, scratch, vegie scraps, rice, & whatever unsuspecting creature wanders into their run. How much should I mix into their feed? Any other suggestions appreciated.
