I'm in my mid-30s and anyone who talks with me for longer than 10 minutes will learn that I have - and love - chickens. It's simply one of the many facts of who I am. Many of my friends are intriqued by my hobby but none have joined me. I know that many think it's "interesting", as in "wow, Jenn is certainly a character, having chickens in the city... better her than us!".
But I don't care. My chickens bring me joy, give me eggs, and provide garden fertilizer that my friends all want.
I know that my coworkers and cousins who are my age think I'm weird for liking chickens.
But then again, their hobbies don't interest me in the slightest. I'll spend my money how I want, and they can spend theirs as they want.
Be who you are and don't aologize for it. You'll be happier and have more time to spend with your chickens when you're not fighting with thses silly people.
