A lot of things we do on the farm are for the experience. My father and I were hobby beekeepers. I still have a couple of hives. With the money we spent on box, frames and an extractor we could have bought all the honey we would ever eat. However it was a bond that he and I shared 40+ years ago and now I can share it with my child. Enjoy the chickens and your time with daughter; that is what really matters.I certainly don't regret getting chickens perhaps 10 years ago, but the reality for us was that they were some very expensive eggs!
Coop, run, feeders, waterers, water heaters for winter, food, bedding, etc added up and I'm sure we never came close to breaking even.
That said, they were a great experience for my 4H / FFA daughter.
