I can relate to the differences in flavor between free-range meat and eggs versus those produced in confinement. Even with free-range, you have a spectrum of how the products taste with some hard to differentiate from confined. The free-range I grew up with had the birds getting most of their nutrition by consuming forages with only small amounts coming from any sort of feed. The areas foraged where more along the lines of pastures and hay fields with a little barnyard action that provided the processed grain component. Even though the birds then and now prefer insect fair over just about anything else, little pieces of vegetative greens dominate by volume what the birds actually consume. Most the time seeds and sometimes fruits come in second. The consistent exception to that pattern is chicks where insects and the like are most important. The impacts on flavor come mostly from the changes in the fat that be related to diet. The forages have a lot more unsaturated fatty acids and less energy coming from carbohydrates. When I pack my birds up on a grain based diet like when they are confined, the types and amounts of the fatty acids in the eggs and meat tends to reflect that of the diet provided. Things get real fun with the dietary carbohydrates which tend to be converted saturated fats for storage in tissues. Those saturated fats are what give the different taste and mouthfeel. The chickens, like most animals, cannot make much in the way of the unsaturated fatty acids that many consumers prefer with respect to taste and health interest. Some do cheat by using unsaturated fat source in the feed formulations. I use things like safflower and BOSS to get closer to the unsaturated fatty acids. With fish I use fish oil and canola oil.
A big part of the corn, at least as I use it, is that it can make the birds fat because the its inclusion can sometimes make so the diet has too much energy. I try to manage shelled corn inclusion rate as a function of the weather. The birds get a fixed rate of the nutritionally balance / complete formulation and I start adding things like shelled corn, millet, BOSS and soaked oats when it get cold. The colder it gets the more of the intact grains the birds get. The problem is the weather changes a lot during the winter and some birds need more or less energy depending upon sex, whether or not in lay, and state of feathering. Birds in the hard part of molt eat more when it is cold. Wind really aggravates things. I try to feed to meet the needs of the neediest which means some are being overfed.
As long as you are feeding the right amount of protein your birds should not be fat. I do not let my birds feed ad lib once grown to breed weight. They get a 1/4 lb feed per bird per day. They do not get fat. I don’t feed corn or scratch. I agree there is a taste difference. I don’t feed boss or the others you mentioned. I do feed dried mealworms or handful of greens as an occasional treat but not every day. They are more confined in the winter but this does not mean I feed more. I occasionally make homemade protein seed cakes for them with dried mealworms in them. Again I don’t dilute the nutrition in the bag. Treats less than 10% of diet. I grow my greens for them. I agree my chickens much prefer to forage but will still eat same amount of food per day. Does take them longer in the day to eat it but still eat same amount. I live on smaller amount of property but when able to forage they love the bugs and insects they can find in the garden or around the house. I just see it as a nice treat for them. I will be interested to see the difference in the egg yolk between winter versus spring/summer when foraging more.
