Hi, welcome to BYC!
Why would a breeder want broilers if not for eating? Will you have something to do with all the extra boys you hatch? Why RIR??
As much as I love raising chickens, having chicks, broody's and roosters.. one bad roo is enough to ruin the experience for the whole flock. Ugh, I resent the one that crows specifically at me. At first it was no big deal, but it has gotten old. He was a lap boy, turned back attacker.

Later today..
Sounds to me like you are pretty gung ho about the whole farming thing! Me to.

I'm gonna have to suggest that you slow your roll and take one experience at a time instead of getting overwhelmed. Spread out the joy and excitement a little! Farming is A LOT of work.
So get yourself some hens and raise them this year, persue your cow if you want... but wait until your girls are grown and you got your system running well before you add any boys. (ESPECIALLY if you don't have previous chicken experience) They ALWAYS mature faster and become ready to mate sooner than the females. If you wait till the girls are older and more confident they will do a better job keeping him in check and teaching him some manners. And if you don't already have chickens... get a variety and see which one you really enjoy! Trust me when I say chickens aren't always in person what they appear to be on paper. Having a variety on pasture is fun and easy to tell them apart as well as possible easy to tell who laid what egg, making it ultimately easier to tell if someone is having health or laying issues. Plus I feel like a kid when I get to see what colors I collect every day!

And if it RIR you want... make sure that's what you are getting and not some other version that is mislabeled. On paper, I like the New Hampshires... I got production reds which according to the hatchery area cross between RIR/NH. I ecpected to like some breeds less and some more, but end up surprised sometimes.. you just never know!

Got a white leghorn because she was supposed to lay early but be flighty. Figured she would be the first over the fence and gone to a predator. She didn't lay until 22 week, was flighty, but also very cool looking and great member of the flock and white ended up being an important color to my egg basket.

Will never have a flock without at least some EE, they are a real mixed bag of personality.
Good luck and best wishes!
