Since you are inexperienced, you might not want a rooster right now- there is a learning curve. Also, male chickens raised in a mixed age flock often act better bc the older females teach the young boys some manners.
we started out with 4 males snd 15 females. Some were straight run breeds. Around 12-14 weeks of age, one breed became aggressive-they matured early, they were mean. We butchered the males and cooked them. In our inexperience, we did not let them rest. At the young age of 14 weeks, they were stringy and tough, so rest any butchered birds for 2-3 days after butchering. Then we were left with 2 males in a flock of all same age chickens. One quickly took the lead, but became aggressive towards our tween child, so we removed him. If you have children, be aware that young children are at eye level for an attack by an aggressive rooster. Even with a lot of land, some roosters will seek out confrontation bc they are aggressive and you don’t young children the focus of any aggression.
the remaining rooster in our first flock stayed for a year, but we removed him bc he became more aggressive, and had me in his sights always (not the kid!). So once we had a younger male ready to take over that second rooster was removed. The younger male (now the third rooster in the flock) was amazing!!! After getting his a$* handed to him repeatedly by the older hens and head rooster for months, he was quite the perfect flock leader! We kept him for about a year and then let another male take over (head rooster #4). Unfortunately that rooster just died unexpectedly!! So we are rooster-less ATM.
we have actually had several more males in our flock due to straight run, but they come and go around 4-5 months of age. We have switched out roosters also bc my kid is involved in 4-H and shows chickens.
Currently we have 15 (yes, 15) males that are 14 weeks old. They have been raised separately. We bought only sexed males bc that was the only option available at any hatchery last July!! We bought 8 breeds and 1 surprise chick. We ended up with one accidental female (missexed). We have now picked 3 males and the female to integrate into the flock. The other males will be raised for another few weeks then butchered or we will take to sell. In the spring we will likely remove 2 of the males, otherwise there will be too much fighting. Right now, in lower light fall/winter they are less prone to fight.
selling: Know that most males will get eaten by whomever buys them. I take mine to a livestock auction where the auction house takes a 25% commission, but hands me cash at the end (or mails me a check if I don’t stick around). Your selling price varies by who is there bidding. I know some of our males have gone to live in flocks, others went to become meat. The last rooster we sold -thegreat rooster #3 above - ended up as meat, despite my bringing him to auction early (more views and early in the lineup), tagging him with clear info that he was a good temperment, and caging him separately in a roomy cage...but it just happened that no one needed a flock rooster. Another rooster we sold went for quite a bit of money bc he won “Grand Champion” and was labeled as such. We have friends that raise up chickens and then post on CL and sell them forusually $5/head to individuals that will butcher them for meat, or who feed their dogs a “raw food diet”. We know someone else who has released his chickens into the woods/property of a relative when he was done with chickens ... so they entered the wild animal food chain eventually -rather like a free-ranging flock without the coop at the end of the day. Basically, you have a lot of options.
Good luck with your flock!
