Okay so i need to feed my chickens laying pellets but i also have a rooster in the same pin and he eats with them. And they eat the grower pellets from his feed bowl. And they also get crushed corn as a treat and some scraps. They are all about a year or so..(got them from someone who cant care for them any longer) So question... Can i just feed them all laying pellets and treats once in a while and completely stop the grower? Is that enough for the roo? I will also buy a little oyster shell for treats.
