We have a lot of sand in FL, I used to think it counted as grit but it really doesn't. Learned the hard way with repetitive crop issues. Putting out insoluble granite has proven a good preventative for mine, and they actually consume a lot of it compared to what others report. 2-3 bags / year.
We feed 20% All Flock. Oyster on the side.
I do have one feeder (out of 5) that I put a scoop of Layer in for one silly old girl who came here as an adult and has never understood oyster shell. She lays terrible soft eggs otherwise and shows signs of arthritis so I worry about her depleting her bones.
I've noticed when they have the option of feeds to pick from, they have the same attitude towards layer as Oyster shell, mostly eating their main feed.
But since some of the other girls help her eat it, I pick a higher protein layer, lately it's been Nutrena Silkie & Ornamental 22% Layer which comes as a "Clean Crumble" basically small balls. My chickens are all LF but really seem to prefer their food in small ball form, lol.
When the chicks are still little (under 2 weeks) I use Nutrena Silkie 24% Starter. Which comes as a teeny tiny balls. It's less messy and there's much less waste over regular crumble.
I consider these extra feeds other than All Flock to be not strictly necessary, extraneous fluff. But it saves me some headaches.
P.S. Do I see a Paso Fino in your profile picture? Hard to tell when it's small, lol.
