This is the nutrition label. 16% protein
tl/dr: I think you have decent baseline feed, but it could use some supplementation that’s reasonably inexpensive and simple to provide.
**********
Ok, that’s not terrible at all. But it’s at the pretty minimal level for protein. And the Ca (calcium) isn’t the highest I’ve ever seen.
The recommended nutrition guidelines for chickens are often on the low side, as the guidelines are traditionally aimed toward mass production growers, giving the absolute minimum to keep the specially-bred production hens alive and laying eggs, until they keel over dead at age 2 - 2 1/2 years or so, or get culled for unacceptably low production. It’s offering the cheapest options for pullets (females under one year of age) to keep them laying and alive. It’s often not enough for them to thrive - they’re still growing, in addition to producing eggs!
The feed looks otherwise decent, but I’d suggest supplementing with *animal* protein, that derived from mammals, birds, fish, etc., plus maybe more calcium (Ca.) Think ground beef, canned tuna and sardines, scrambled eggs, etc. (You don’t want to see my girls when offered deli turkey.

) You also should be offering oyster shells (maybe the flaked ones if they don’t like the chunk version), plus any eggshells from your kitchen. The calcium helps form strong shells, and also helps stimulate the contractions to move eggs along the internal pathway for laying.
Many people say that you should cook the eggshells first, but I just put a bunch of them in a ziplock bag, close it, and crunch the heck out of them.
