I feed my 12 or 13 layers all the laying pellets that they eat in a day about 4lbs. any more and I have to pour it back in the feed barrel at night so the varmints don't come in get them a gut full at night. All my other little whatchamacallits run pretty much wild they get whatever, whenever, usually only at grain feeding time and believe you me they are a waitin' right there on time. So I don't think a 1.5 lbs. of grain twice a day is a lot of grain for 25 or so chickens. I don't mix it all together for the hens to just fill up on and not eat their pellets. I think they lay just fine and they aren't fat fat just really healthy. If they are producing they'll use all the littlie goodies that's in grain it yellows the yolks up or I might say "oranges" the yolks up the way all my egg customers like'm.
I think if they wanted ol' pale, pukey, colored egg yolks, they can get them cheap at the grocery store they got a bunch of them. As far as the fat in the grain they will burn alot of that up out scratching and searching for bugs, grass, and who really wants to know whatever else they eat.
I feed mine grain and all I know it works. I think its a good additve to those old soy meal, fiber filled, barely have enough alfalfa clover in them to make them kinda a greyish-green colored layer pellets.
I'll stick to my ratio (which is not for everyone) of feeding for now, till somebody proves otherwise. Alot of people ask me every winter how do you get your hens to lay eggs all winter. I simply reply I feed mine. Got eggs?
P.S. Don't forget to eat your Peanut Butter and Bananna sandwiches. They're good for ya.
