Good for you, parental figure! Welcome to BYC.
Here are my favorite beginning articles (though asking your son might do as well for some of this, we all know how that can go). All articles are short, and have illustrations, and reviews, which are often worth looking at for the comments.
3. Ventilation (important to chicken health), with helpful links to coop designs organized by climate (because what is just right for my New England hens won't work for my brother's Arizona chickens)
6. (are you where winter is starting??) Winter chicken care
To look for articles on your own:
A. Use the SEARCH button, but use the
Advanced Search choice, and
select ARTICLES at the top of the box. Just enter your keyword(s) and scroll through your results!
B. I find it helpful to notice the rating and reviews. All articles are by BYC members, and all the reviews/ratings are as well. The ratings help a newbie like me sort the most useful and reliable articles.
C. You can
bookmark the articles or posts you think you want to refer to again using that bookmark icon at the top of articles or posts. You can find them again by clicking on your own avatar and looking at the list of bookmarks you have built up!
