Beyond my skills, no knowing what you have available, or pricing/budget. There may be a language issue, as well - here "corn" and "maize" are the same thing.
Superficially, you can't make a complete feed with any combination of the things listed. Protein levels are too low, even before considering essential amino acid profile of the protein, mineral content, and trace nutrients.
Here in the US, the generally accepted targets for adult layers is 16% protein (18-20% is prefered), 3-4% fat, fiber recommendations vary considerably, but 3-4% is again a good target. If you can offer supplimental calcium (crushed oyster shell, calcium diphosphate, dicalcium phoshate) you don't need to concern yourself with that in the feed. Our freinds across the pond make due with lower protein % (13-15%) by adding synthetic amino acids - not available for home use.
So, accepting that there is variation between crops, and sources of nutrition data vary, we can still offer a general gloss of what you have to work with there.
Wheat grains are around 12.5% protein, 2.6% fiber, 2% fat.
If you can get durum wheat, its about 16.5% protein, 3% fiber, 2% fat
Maize/Corn is 8.5-9.5% protein, 2.5% fiber, 4.5% fat
(Finger) Millet is around 9% protein, 5.5-6% fiber, 1.5% fat
(Brown) Rice is around 10.5% protein, 2.0% fiber, 2.0-2.5% fat
I understand Pakistan grows a decent amount of rape for making oil, and also barley. Rapeseed forage is high protein, 19-20%, high fiber 16% +/-, low fat 2%. Barley grains are about 12% protein, 5% fiber, 2% fat. Also something called "gram" seeds? My source indicates that's around 24% protein, 6.5% fiber, 1.5% fat. If you can get spent brewers grains, dried, that's another high protein source with most of the sugars removed.
Essentially, you are looking to balance some combination of the above, targeting the numbers I offered, an amino acid profile I've not yet offered, and a total daily caloric intake as well.
Making feed at home is hard - we can't do it here efficiently, effectively, or at reasonable cost. For you, I don't see how you get close to targets without mixing some combination of hard wheat, maize/corn, dried rapeseed forage, and black gram seeds. While I could play with the ratios, and hit theinitial targets, without kjnowing cost per pound, no way to guess if its economical - no point in continuing to make up an amino acid profile to see if it checks those boxes, too. Chances are, it would not. Likely not on trace minerals either.
