You're going to have to sell them cheap until you know the gender, a lot of people want to know what they're getting.
I would try craigslist @ $40 for all or $5 each, minimum 2. Gender matters, $15 per pair is the average I see around here for bantam pairs. But good luck getting the $5 for just the boy. But add a hen and $10 to the price, and you have better luck.
For the add, I find that sales happen faster the more specific I am. Decent pictures, age, best guess on gender (unless known), type of feed they've been on, and their environment. It should go without saying, but I throw in "Bright eyed and healthy" or some other mention of their general health and conditions. Say everything you can about them honestly.
Set up a junk email account and don't use your good one, in case of spam. Put your phone number in the add. I've never sold anything via email... if they're serious, they'll call. If they're spam, they'll write one sentence. Kids without parent supervision will also email. Some people scramble their phone number, a mix of number and written numbers, like 5 one 3. Not sure why they do that, I haven't gotten any spam calls.
If you have extra roosters, mention them to everyone who shows up to buy something else! You never know. I had a lady come for a trio of Naked Necks and she took my 3 EE cockerels too.
