LOL!Or some chickens!
True wisdom there!Don't sell yourself short.
Keep your eyes open for a second-hand incubator, set it up & make sure it's working right, set half a dozen of your own eggs, and get your feet wet. All the books in the world won't beat experience. Get stuck?...ask for help, and think like a broody hen.
My "horse chickens" have a rooster...all are eating the same layer pellets...never had a problem with "him" only eating that
The damage is internal and is not something you really recognize as what it is without a necropsy when the bird dies -- what is found is evidence of various internal issues caused by the diet that have caused the life to shorten fairly considerably to what it could have been on a more appropriate diet.
