Hi - I have 30 birds -- 11 are over 2 years old and 19 are 16 weeks old. I have been feeding Flock Raiser and have just started adding oyster shells for the laying hens. I want to switch feed to either the Soy-free layer from Coyote Creek Farm - http://coyotecreekfarm.org/ or maybe the Lay Crumbles from Texas Natural Feeds - http://www.texasnaturalfeeds.com/ .. My birds have the run of 60' x 90' with trees to climb and bugs to eat. They are locked-up in their coop at night. ............or maybe I should just make my own feed !!?? Any thoughts ?? Thank you, Dave Strickland Oklahoma
