I know, but that's literally what's on the bag, "Meatbird Crumbles." I guess I could add that I buy the Rural King house brand, Country Roads. But I always check the tags, that's how I ended up going with the Meatbird, as it's the only product available in my area that actually includes animal protein. I suppose I could shop around at the farther stores and find a Gamebird feed, and then cut it with a Chick Starter, but that's a lot more driving and faffing around. I do wonder about the vitamin/mineral profile because it IS meant to be fed to broilers with an expiration date on their little lives, which is why I want to get some Nutr-Drench to add here and there
I can't remember if you said what you currently feed, is it a layer crumble or pellet? What you could do is just add a little animal protein for a couple weeks before you plan to collect hatching eggs, something like a decent quality dog food, or if you have extra eggs (or if stores put them on a fire sale under a dollar a dozen like they do here) you can give them some boiled egg daily for a couple weeks ahead. That should cover it pretty well without really making a drastic change to what you're already feeding.
