The thought of raising chickens and having your own fresh eggs is intriguing and kind of exciting at first.
When chickens begin to lay, they're generally good for one egg a day, on average.
So figure your needs from there.
You don't need any roosters, unless you hope to hatch some chicks, which is getting harder and harder to do since they're trying quite hard to breed out broodiness in chickens.
Roosters are loud, crow all day and night (not just at sunrise) and can be real assholes.
If chickens don't become broody, they don't sit on eggs.
Broody chickens can become quite bitchy, as well as a real handful.
My wife and I did the chicken thing for a number of years.
First off, chickens are rather filthy animals.
If you plan on keeping them in a coupe with a run, then there is the smell, and the smell brings hordes of flies.
If you don't have predators, you might be able to let them free range, which means letting them spend most of their time outside the pen. They will return in the evening.
Allowing them to free range will lower food costs greatly, providing there are things for them to eat.
It will also disperse the concentration of excrement you would experience from keeping them confined.
We have coyotes, so we couldn't allow free ranging.
If you have coyotes in your area, you will need to provide a very sturdy pen and coupe to keep them, or foxes, or what have you out.
They need a constant source of clean water, that can be prevented somehow from freezing in the winter, if you have such.
They may also need some extra light during the winter months to keep egg production up. (Low light during winter means less eggs)
You may also need to provide some heat during the winter as well.
It's helpful if you have some friends or folks close by that might help you by taking extra eggs off your hands when you begin to tire of eating so many eggs.
As I said previously, we did it for a number of years.
We finally gave our flock away last fall.
We got fucking sick of eggs, the smell, the noise lost it's romance, and the price of feed soared to the point that it was no longer worth the return.
These are only a few of the aspects of raising chickens.
There are many others such as health, chickens that eat their own eggs, bug infestations, cost for bedding, and the list goes on.
When we first got into it, we thought it was great.
By the time we quit, I was certain I'd never eat another egg or chicken ever again.
But that didn't last long.
Since you're into forums, I'd highly suggest one called backyard chickens.
I learned everything that I know about chickens from there.
It's fun, it's rewarding, it's work, it's dirty, it comes at a cost, but there's nothing like an egg that hasn't been in storage for month or so like you get at the grocery sometimes.
