Not so many years ago, it was very common for people to keep chickens in their yards. Most people had them. My grandparents did, and since I got chickens, my Dad loves to tell me chicken stories from his youth. I think most homes back then had chickens, and all of the men and women knew how to raise and feed them, gather the eggs, slaughter and clean the fowl. During the World Wars, there was propaganda encouraging people to tend chickens for the war efforts.
Today we have to do research to find out how to care for chickens, but back then it was learned naturally, passed on from mother to daughter and father to son. It's no wonder there are so many phrases in our language that have to do with chickens or eggs. These phrases were commonly used and understood by everyone because they were shared lessons learned at home. This list is not exhaustive, but just off the top of my head, look at all the chicken/egg phrases we have used for generations. You can apply the meanings, because I'm sure you know them:

We still use and understand these phrases today. The art of raising chickens may have decreased over the years (thank goodness, it's coming back), but the vocabulary hasn't. I call it Chicken Talk, and we all use it. I played around with putting these phrases into artwork that I could frame and display in my home. You're welcome to download and print it for yourself. I shared a plain copy and one that has a computerized frame around it. I made it from scratch and think it's something to crow about, but if you think I laid an egg, don't brood over it.
