Also, we are trying to avoid factory farmed meats and any of the by products from that industry. But most commercial chicken feed contains animal protein.
The majority of chicken feed available to me have ZERO animal byproduct.. noting that chickens are NOT vegetarian and NEED some animal derived amino acids which are synthetically added. I know you give bugs also.
Remember, even though you're buying layer feed or all flock, you're not giving your birds the daily antibiotics
But do YOU remember that poultry in the US is also NOT given daily antibiotics and in fact it's against the law now!
I would supplement meal worms and red worms.
I love growing meal worm AND red wigglers.. if your bird eat them.. it's proof your pasture isn't loaded. Meal worms are WAY too slow of turn around to be a viable chicken feed source. They also are not really high in nutrients even when so called "gut loaded". They require their own housing, maintenance, feed source.. and lettuce is JUST a water source for them as well.
When I lived in the irrigated desert on a city lot.. my birds loved the red wigglers I kept in a composting bin. At my new property that's quite lush a large portion of the year with diverse bug and plant life.. they turn their nose up like.. meh, where's the good stuff! Move anything sitting on the ground and the worms and bugs abound. Worms and bugs.. protein and fat yes.. a great TREAT.. for DOMESTIC chickens which are far more prolific layers than truly wild free range birds.. If THAT is your goal, then research appropriate breeds and go with something much lighter bodied.
I just wonder...when was formula feed developed?
And how many small farmers around the world have access to bagged pellet feed?
Probably when chickens started popping out close to 300 eggs per year and kept in confinement to feed the masses of people that continue breeding out of control. Folks keep chickens as pets and for entertainment instead of as a NEEDED food source, we keep MORE than we need, because we feel entitled to do so. So basically.. when people stopped hunting gathering or wondering where their next meal was coming from. It true developing country small farmers don't have the options we do.. They also don't keep fat fluffy bottom rounded birds or eat them for dinner every day the way WE do.. They eat meat on occasion and their birds are smaller bodied requiring less forage overall. Today's average breeds would require at least an acre per head.. AND they would need to be taught earlier (maybe by a mother hen) what things to forage for. A chick raised with no mum and indoors in a brooder will be *less* adept at ranging.
As one poster shared their heartbreaking story.. and I noted, I'm sure.. genetics does matter. You gals, had their breed going against them already.. though slightly different than Orp.. they aren't known for their longevity.
Lettuce is very healthy for my other stock of various invertebrates.
If you're talking about meal worms, darkling beetles, or red wigglers.. lettuce is not really anything other than a water source. It's consider low nutrient.
I just thought they needed some greens, but maybe not as much as I provided
Common misconception! Lettuce are NOT greens.
Maybe mustard greens or spinach.. clover, cilantro, basil, parsley??
Definitely alfalfa is a green. Or at least it's a grass.. please remember that chlorophyll does NOT indicate nutritive value... And MY information on sprouting says there is equal nutrients with less (mold) issues when sprouts are done only until day 3 verses day 7 of fodder with full "greenness"..

The misconception I speak of though is that chickens need some green. Formulated rations are done so to MEET the need of poultry in captivity BY LAW according to the species and age specified on the label.
Some "green" definitely benefits the enrichment value when offered as a hanging head etc as a TREAT. Fodder trays are all the rage.. My birds, pick the seed off and leave the green behind, making anything beyond soaking the seed for a very short sprout a waste of MY time.. my birds have access to pasture all day.. and sprouts grow WAY to slow in MY temperatures. I still do it because I enjoy the experiments and have fun feeding it out. But it is NOT a means of saving money and will NOT likely impact overall health of a bird. My time is not free. The richness in egg yolk color comes from eating a WIDE array of forages and can be impacted by many things including falsely darkened with added marigold into the feed and things like using a feed based with yellow corn instead of white corn or wheat.. which might produce platinum colored yolks.. cool, but freaky!
I would venture a guess to say.. genetics complicated by malnutrition or vice versa and there could be more to the story that hasn't yet been realized... according to all the information I have seen.. Sorry you lost the 2nd girl.
I can tell from all your replies that you are going to do your very best to get things right! You got lots of good feedback on making your own feed and you MAY still be able to pursue that in the future. But taking it back t basics right now, research avian nutrition and what resources you will have available if you try to go that route. Some "small" farmers these days are getting feeds milled to their specs also. I don't have that option at my current location. But with the BYC world at your finger tips I hope you and your flock will continue to grow into everything you dream it can be!
