Hello Honey,
There is a lot more to raising chickens than you can imagine. I've raised chickens for at least 14 years and I am still learning. I have gone both routes, buying chicks and hatching my own. There a many different breeds of chickens and the personalities of the breeds, bird weights, and egg laying production will vary from breed to breed. For example, the Leghorns are flighty and not very friendly but will lay a lot of large white eggs. Because they are a small chicken, they will easily fly over a 4' high fence. On the other hand, brown egg layers like the Australorp, Brahmas, Orpingtons are heavier birds, cannot fly and are generally very friendly. I have some at this time that are about 7 years old, they stopped laying, but they will still come to me and sit on my lap from time to time.
I will tell you up front, there is nothing like a fresh egg for breakfast and if you raise your own chickens, you know what you are eating, but don't think you are going to save money raising your own. You will be lucky in the long run to break out even when you consider the feed and some meds you will need along the way. (and that doesn't include the cost of a chicken coop you may have to build). My chickens give me a lot of entertainment and I spend a lot of time with them, but now that they are older and don't produce eggs anymore, they are just pets and no egg income.
To maximize egg production, the chickens should have about 14 hours of light, either sunlight or light from a light bulb. The chickens need a shelter to protect them from the elements and to roost at night and not have to worry about raccoons, skunks, foxes, owls, oppossums, dogs, bobcats, etc.
Attached is a photo of my chicken coop which is heated in winter and has exhaust fans for cooling in the summer. The fenced-in run is protected by a 6,000 volt electric fence to ward off predators.
You can email me to get my phone number and I will give you as much info as you need to know about raising chickens. I live in Connecticut.
