Glad to meet you, and welcome to BYC. Best wishes for all ladies! Use that link to tell gender, though it's hard until they get 5-7 weeks old.
Between 5-7 weeks, you should be able to begin visually distinguishing males from females. Compared to pullets, the combs and wattles of cockerels often develop earlier and are usually larger and brighter. Females are typically smaller in size than males. In most breeds of chickens (including yours), you can also begin to see the difference between male and female feathering (not even waiting for those gorgeous tails to come in). Do not try vent sexing at home - it requires a good deal of training, and you can hurt your bird if you don't know what you are doing! Here is another post about sexing chickens.
If you end up with too many roosters, you can rehome them (or eat them if you are so inclined). Rehoming works best using your local Craigslist and Facebook Poultry group. You can also post them here. In all cases,
1. Note in the title of your post WHERE you are located (just your town or county, and state).
2. Include the best glamor shots you can get of those bad boys to help them get a good home rather than a soup pot or limbo at an animal shelter.
3. Tell all info you would want to know if you were shopping for a rooster:
a. breed, health & age
b. where you got the rooster
c. temperament - how does that rooster behave with people, children and other chickens and roosters?
d. why are you getting rid of the bird.
Best wishes from New England. May the odds be with you!
Welcome. I agree with @janiedoe. If you get more than one rooster, you can have a bachelor coop/run. I have been doing this for awhile and am just getting to the point where my hen ratio will allow them to be together.
