A good overview touching on incubators, comparing breeds of layers, and feed.
I would note where "mash" is mentioned, most of us call their crumbles or pellets mixed with water "mash," so I was guessing your mash is made of scratch maybe as otherwise, there's nothing to pick out of the traditional mash. Mash is a staple with all of ours, as they're spoiled.
Also, I would add where you say extra roosters may have to be culled
or rehomed.
You
could add that after 12 weeks (or from the day they hatch), all-flock is a choice as it's better for roosters due to less calcium and it can be fed from day-old chicks to old chickens. With that you have to provide an oyster shell to laying hens. That's fine explaining how you do it, but there are options in a few places that would enhance your article.
