Glad to meet you, and welcome to BYC. Chickens are so awesome, aren't they? There are a number of gardeners here on BYC. There is even a gardening forum just to discuss it. There are several posts about gardening for or with chickens.
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!
Welcome. I am so sorry for you and all of the Texas members who are experiencing unrelenting high temperatures. It is really hard to try to keep the chickens cool in this weather.
