OK, I know that Flock Raiser and Layena are not the same thing. I'm feeding 20 pullets (who are beginning to lay) + 1 Rooster + 1 Drake + 5 ducks (who are also laying). They share an inside area but they have separate pens so the ducks cannot get to the chicken food. We feed all of the birds Flock Raiser mixed with whole oats to get the protein down to about 16%. We supplement with grit and oyster shell - free choice. Now that they are beginning to lay do we change the chickens over to layena or can we keep them on the Flock Raiser (which would be easier for us?). Advice please, I'm heading out to get feed tomorrow night. Thanks!
